MEMORANDUM AND ORDER

WILLIAM J. NEALON, District Judge.

BACKGROUND

The above-captioned action is one seeking review of a decision of the Commissioner of Social Security (“Commissioner”) denying Plaintiff Roderick Clinton Jenkins’s claim for social security supplemental security income benefits. For the reasons set forth below the decision of the Commissioner will be affirmed.
Supplemental security income (SSI) is a federal income supplement program funded by general tax revenues (not social security taxes). It is designed to help aged, blind or other disabled individuals who have little or no income.
Jenkins was born in the United States on December 13, 1972. Tr. 149.1 Jenkins attended regular education classes until he was taken out of school and incarcerated during the twelfth grade. Tr. 55, 169 and 177. Jenkins testified at the administrative hearing which was held in this case on June 16, 2009, that he did not obtain a General Equivalency Diploma (GED). Tr. 55. However, he previously told Ali Nourian, M.D., who examined Jenkins on behalf of the Bureau of Disability Determination2 that he obtained his GED while incarcerated. Tr. 298. Jenkins admitted that he can read, write, speak and understand the English language. Tr. 167 and 201.
The record reveals that Jenkins has a long history of criminal activity as well as a history of using cocaine, crack and marijuana. Tr. 248, 258, 408, 413 and 494-495. His criminal history includes convictions for aggravated assault and drug trafficking. Id. He reported that he last used cocaine and marijuana in early 2006. Tr. 489 and 494.
Jenkins has a limited work and earnings history. Tr. 157-163. He has past work experience as a dishwasher, packer, construction worker, and a telemarketer. Tr. 169. He also worked for various temporary employment agencies. Id. Records from the Social Security Administration indicate that he worked in 1987 earning $257.95, 1992 earning $1264.80, 1993 earning $1403.43, 1994 earning $2098.74, 1998 earning $6221.29, 1999 earning $9170.79, 2000 earning $7446.85, 2001 earning $520.00, 2006 earning $11,456.00, and 2007 earning $327.25. Tr. 157. His total earnings were $40,167.10. Id. A vocational expert testified that all of Jenkins’s past employment was unskilled, sedentary to medium work.3 Tr. 75-76.
*213On February 27, 2007, Jenkins protectively filed4 an application for supplemental security income benefits. Tr. 13, 149-156 and 197. Jenkins alleges that he became disabled on October 1, 2002, because of an HIV infection and mental illness. Tr. 91 and 168. He contends he has blackouts, seizures, migraines and fatigue. Id. The record reveals that Jenkins last worked in 2008. Tr. 15. In that year Jenkins started a masonry business. Id. The administrative law judge found that this work was substantial gainful activity but that because it “was short-lived and ceased” it “would likely be considered an unsuccessful attempt to return to work.” Tr. 15.
Jenkins’s alleged disability onset date of October 1, 2002, has no impact on Jenkins’s application for supplemental security income benefits because supplemental security income is a needs based program and benefits may not be paid for “any period that precedes the first month following the date on which an application is filed or, if later, the first month following the date all conditions for eligibility are met.” See 20 C.F.R. § 416.501. Consequently, Jenkins is not eligible for SSI benefits for any period prior to March 1, 2007.
On June 13, 2007, the Bureau of Disability Determination denied Jenkins’s application for SSI. Tr. 13 and 91-95. On August 13, 2007, Jenkins requested a hearing before an administrative law judge. Tr. 96. After approximately 22 months had passed, a hearing was held on June 16, 2009, before an administrative law judge. Tr. 25-81. On June 25, 2009, the administrative law judge issued a decision denying Jenkins’s application for SSI benefits. Tr. 13-24. On August 21, 2009, Jenkins filed a request for review of the decision with the Appeals Council of the Social Security Administration. Tr. 7-9. After 13 months had passed, the Appeals Council on September 21, 2010, concluded that there was no basis upon which to grant Jenkins’s request for review. Tr. 1-4. Thus, the administrative law judge’s decision stood as the final decision of the Commissioner.
On November 19, 2010, Jenkins filed a complaint in this court requesting that we reverse the decision of the Commissioner denying him supplemental security income benefits. The Commissioner filed an answer to the complaint and a copy of the administrative record on January 31, 2011. Jenkins filed his brief on April 15, 2011, and the Commissioner filed his brief on *214May 18, 2011. The appeal5 became ripe for disposition on June 6, 2011, when Jenkins elected not to file a reply brief.

Standard of Review

When considering a social security appeal, we have plenary review of all legal issues decided by the Commissioner. See Poulos v. Commissioner of Social Security, 474 F.3d 88, 91 (3d Cir.2007); Schaudeck v. Commissioner of Social Sec. Admin., 181 F.3d 429, 431 (3d Cir.1999); Krysztoforski v. Chater, 55 F.3d 857, 858 (3d Cir.1995). However, our review of the Commissioner’s findings of fact pursuant to 42 U.S.C. § 405(g) is to determine whether those findings are supported by “substantial evidence.” Id.; Brown v. Bowen, 845 F.2d 1211, 1213 (3d Cir.1988); Mason v. Shalala, 994 F.2d 1058, 1064 (3d Cir.1993). Factual findings which are supported by substantial evidence must be upheld. 42 U.S.C. § 405(g); Fargnoli v. Massanari, 247 F.3d 34, 38 (3d Cir.2001) (“Where the ALJ’s findings of fact are supported by substantial evidence, we are bound by those findings, even if we would have decided the factual inquiry differently.”); Cotter v. Harris, 642 F.2d 700, 704 (3d Cir.1981) (“Findings of fact by the Secretary must be accepted as conclusive by a reviewing court if supported by substantial evidence.”); Keefe v. Shalala, 71 F.3d 1060, 1062 (2d Cir.1995); Mastro v. Apfel, 270 F.3d 171, 176 (4th Cir.2001); Martin v. Sullivan, 894 F.2d 1520, 1529 & 1529 n. 11 (11th Cir.1990).
Substantial evidence “does not mean a large or considerable amount of evidence, but ‘rather such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.’ ” Pierce v. Underwood, 487 U.S. 552, 565, 108 S.Ct. 2541, 101 L.Ed.2d 490 (1988) (quoting Consolidated Edison Co. v. N.L.R.B., 305 U.S. 197, 229, 59 S.Ct. 206, 83 L.Ed. 126 (1938)); Johnson v. Commissioner of Social Security, 529 F.3d 198, 200 (3d Cir.2008); Hartranft v. Apfel, 181 F.3d 358, 360 (3d Cir.1999). Substantial evidence has been described as more than a mere scintilla of evidence but less than a preponderance. Brown, 845 F.2d at 1213. In an adequately developed factual record substantial evidence may be “something less than the weight of the evidence, and the possibility of drawing two inconsistent conclusions from the evidence does not prevent an administrative agency’s finding from being supported by substantial evidence.” Consolo v. Federal Maritime Commission, 383 U.S. 607, 620, 86 S.Ct. 1018, 16 L.Ed.2d 131 (1966).
Substantial evidence exists only “in relationship to all the other evidence in the record,” Cotter, 642 F.2d at 706, and “must take into account whatever in the record fairly detracts from its weight.” Universal Camera Corp. v. N.L.R.B., 340 U.S. 474, 488, 71 S.Ct. 456, 95 L.Ed. 456 (1951). A single piece of evidence is not substantial evidence if the Commissioner ignores countervailing evidence or fails to resolve a conflict created by the evidence. Mason, 994 F.2d at 1064. The Commissioner must indicate which evidence was accepted, which evidence was rejected, and the reasons for rejecting certain evidence. Johnson, 529 F.3d at 203; Cotter, 642 F.2d at 706-707. Therefore, a court reviewing the decision of the Commissioner must scrutinize the record as a whole. Smith v. Califano, 637 F.2d 968, 970 (3d Cir.1981); Dobrowolsky v. Califano, 606 F.2d 403, 407 (3d Cir.1979).

Sequential Evaluation Process

To receive disability benefits, the plaintiff must demonstrate an “inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months.” 42 U.S.C. § 432(d)(1)(A). Furthermore,
[a]n individual shall be determined to be under a disability only if his physical or mental impairment or impairments are of such severity that he is not only unable to do his previous work but cannot, considering his age, education, and work experience, engage in any other kind of substantial gainful work which exists in the national economy, regardless of whether such work exists in the immediate area in which he lives, or whether a specific job vacancy exists for him, or whether he would be hired if he applied for work. For purposes of the preceding sentence (with respect to any individual), “work which exists in the national economy” means work which exists in significant numbers either in the region where such individual lives or in several regions of the country.
42 U.S.C. § 423(d)(2)(A).
The Commissioner utilizes a five-step process in evaluating supplemental security income claims. See 20 C.F.R. § 416.920; Poulos, 474 F.3d at 91-92. This process requires the Commissioner to consider, in sequence, whether a claimant (1) is engaging in substantial gainful activity,6 (2) has an impairment that is severe or a combination of impairments that is severe,7 (3) has an impairment or combination of impairments that meets or equals the requirements of a listed impairment,8 (4) has the residual functional capacity to return to his or her past work and (5) if not, whether he or she can perform other work in the national economy. Id. As part of step four the administrative law judge must determine the claimant’s residual functional capacity. Id.
Residual functional capacity is the individual’s maximum remaining ability to do *216sustained work activities in an ordinary-work setting on a regular and continuing basis. See Social Security Ruling 96-8p, 61 Fed.Reg. 34475 (July 2, 1996). A regular and continuing basis contemplates full-time employment and is defined as eight hours a day, five days per week or other similar schedule. The residual functional capacity assessment must include a discussion of the individual’s abilities. Id.; 20 C.F.R. § 416.945; Hartranft, 181 F.3d at 359 n. 1 (“ ‘Residual functional capacity’ is defined as that which an individual is still able to do despite the limitations caused by his or her impairment(s).”).

When the physician or nurse conducted a review of Jenkins’s systems he denied the following: constitutional, eye, nasal, cardiovascular, respiratory, gastrointestinal, urinary, neurologic, psychiatric and hematologic symptoms. Id.
On August 19, 2008, Jenkins had an appointment at the Scranton Counseling Center. Tr. 488. A mental status examination on that date was normal. Id. Jenkins’s mood was euthymie and his affect appropriate; he was friendly, alert, cooperative, and his concentration and attention were good; he was oriented and non-psychotic; he denied drug and alcohol use; he denied homicidal and suicidal ideations; and he stated that his medications were helpful. Id. Jenkins reported no side effects from his medications. Id. The medical provider27 meeting with Jenkins noted that Jenkins was “doing much better,” “compliant with meds daily,” and his “[t]houghts [were] clear, organized and mature.” Id.
On September 16, 2008, Jenkins had an appointment at the Scranton Counseling Center. Tr. 487. A mental status examination on that date was normal. Id. Jenkins’s mood was euthymie and his affect appropriate; he was friendly, alert, cooperative, and his concentration and attention were good; he was oriented and non-psychotic; he denied drug and alcohol use; he denied homicidal and suicidal ideations; and he stated that his medications were helpful. Id. Jenkins reported no side effects from his medications. Id. The medical provider28 meeting with Jenkins noted that he saw “a dramatic improvement in Rod’s level of maturity, reasoning and judgment.” Id.
On September 24 and 29, 2008, Jenkins underwent a neuropsychological evaluation by John R. Harvey, Ph.D., a licensed psychologist with Allied Services, Scranton. Tr. 519-532. Jenkins was referred to Dr. Harvey by the Lackawanna County Office of Public Assistance to determine Jenkins’s employability. There is no indication in Dr. Harvey’s report of the evaluation that Dr. Harvey reviewed Jenkins’s medical and psychiatric treatment records. It appears that the bulk of the background information set forth in the report was provided to Dr. Harvey by Jenkins. Jenkins told Dr. Harvey that he had a “history of delusional type activity, which occurred well after he refrained from drug use.” Tr. 521. Jenkins further told Dr. Harvey that “[h]e heard voices as recent as a few weeks ago.” Id.
Dr. Harvey administered a battery of intelligence tests and found that Jenkins’s “overall intellectual ability is in the low average range” and that Jenkins “does not meet the diagnostic criteria for a specific attentional disorder.” Tr. 524. Dr. Harvey stated that Jenkins has “weaknesses with expressive and receptive language and verbal memory ... [and] immediate and working memory.” Id. Dr. Harvey stated that Jenkins “has strengths with perceptual reasoning ability, cognitive flexibility, visual memory, serial recall and visualization.” Id.
Dr. Harvey diagnosed Jenkins as suffering from bipolar disorder, psychotic; receptive/expressive language disorder; a history of substance abuse in current remission” and stated that “[t]here is cause to rule out antisocial personality disorder due to his lack of remorse and not follow*224ing social rules as well as hurting others.” Tr. 525. Dr. Harvey in conclusory fashion stated that Jenkins “is unable to engage in meaningful employment.” Id. Dr. Harvey did not provide a funetion-by-function assessment of Jenkins’s mental work abilities as did Drs. Barrett, Nourian and Gavazzi.

Discussion

The administrative law judge at step one of the sequential evaluation process found that Jenkins had engaged in substantial gainful work activity since February 27, 2007, the application date, but that the activity was an unsuccessful attempt to return to work. Tr. 15.
At step two of the sequential evaluation process, the administrative law judge found that Jenkins had the following severe impairments: bipolar disorder and a history of personality disorder. Tr. 15. The administrative law judge found that Jenkins’s HIV disease was a non-severe impairment.29 Id.
At step three of the sequential evaluation process the administrative law judge found that Jenkins’s impairments did not individually or in combination meet or equal a listed impairment. Tr. 15-19.
At step four of the sequential evaluation process the administrative law judge found that Jenkins could not perform any prior work but had the residual functional capacity to perform unskilled work at all exertional levels but with non-exertional restrictions. Tr. 19 and 22. The administrative law judge limited Jenkins to repetitive woi'k in a stable environment; that was predictable and not subject to frequent changes; that was removed from significant contact with the public; that would not involve a great deal of independent judgment and decision-making; and that only involved simple, oral communication rather than written communication. Based on that residual functional capacity, and Jenkins’s age, education and work background, and the testimony of a vocational expert, the administrative law judge found at step five of the sequential evaluation process that Jenkins could perform unskilled work as a bench packager, assembler, and bench inspector, and that there were a significant number of such jobs in the local, state and national economies.30 Tr. 23.
The administrative record in this case is 532 pages in length and we have thoroughly reviewed that record. The administrative law judge did an adequate job of reviewing Jenkins’s vocational history and medical records in his decision. Tr. *22515-24. Furthermore, the brief submitted by the Commissioner thoroughly reviews the medical and vocational evidence in this case. Doe. 12, Brief of Defendant. Jenkins’s primary argument is that the administrative law judge erred by rejecting the opinion of Dr. Harvey and relying on the opinion of Drs. Barrett, Nourian and Gavazzi. Jenkins also argues that the administrative law judge erred in finding that he was not credible. We have thoroughly reviewed the record in this case and find no merit in Jenkins’s arguments.
Initially it should be noted that no treating physician has indicated that Jenkins is unable to engage in full-time employment because of his physical and mental impairments. Dr. Harvey, although an examining psychologist, was not a treating psychologist and no special deference is due his opinion as opposed to Drs. Barrett, Nourian and Gavazzi. Furthermore, Dr. Harvey’s opinion regarding Jenkins’s ability to work is conelusory and he fails to provide a function-by-function assessment of Jenkins’s mental work abilities in contrast to the assessments of Dr. Barrett, Nourian and Gavazzi. Jenkins, in his brief, focuses on his mental limitations and does not challenge the administrative law judge’s decision as to his physical abilities. Even if Jenkins did challenge the decision of the administrative law judge regarding his physical abilities, the medical records reveal that Jenkins’s HIV infection was well-controlled. Furthermore, the treatment records from Scranton Counseling Center show that Jenkins repeatedly had a normal mental status and at most moderate limitations in mental functioning.
The administrative law judge stated that Jenkins’s statements concerning the intensity, persistence and limiting effects of his symptoms were not credible to the extent that they were inconsistent with the ability to perform work as a bench packager, assembler, and bench inspector. The administrative law judge was not required to accept Jenkins’s claims regarding his limitations. See Van Horn v. Schweiker, 717 F.2d 871, 873 (3d Cir.1983) (providing that credibility determinations as to a claimant’s testimony regarding the claimant’s limitations are for the administrative law judge to make). It is well-established that “an [administrative law judge’s] findings based on the credibility of the applicant are to be accorded great weight and deference, particularly since [the administrative law judge] is charged with the duty of observing a witness’s demeanor..." Walters v. Commissioner of Social Sec., 127 F.3d 525, 531 (6th Cir.1997); see also Casias v. Secretary of Health & Human Servs., 933 F.2d 799, 801 (10th Cir.1991) (“We defer to the ALJ as trier of fact, the individual optimally positioned to observe and assess the witness credibility.”). Because the administrative law judge observed Jenkins when he testified at the hearing on June 16, 2009, the administrative law judge is the one best suited to assess the credibility of Jenkins
Our review of the administrative record reveals that the decision of the Commissioner is supported by substantial evidence. We will, therefore, pursuant to 42 U.S.C. § 405(g) affirm the decision of the Commissioner.
An appropriate order will be entered.

ORDER

In accordance with the accompanying memorandum, IT IS HEREBY ORDERED THAT:
1. The Clerk of Court shall enter judgment in favor of the Commissioner and against Roderick Clinton Jenkins as set forth in the following paragraph.
*2262. The decision of the Commissioner of Social Security denying Roderick Clinton Jenkins supplemental security income benefits is affirmed.
3. The Clerk of Court shall CLOSE this case.

.The terms sedentary, light and medium work are defined in the Social Security regulations as follows:
(a) Sedentary work. Sedentary work involves lifting no more than 10 pounds at a time and occasionally lifting or carrying articles like docket files, ledgers, and small tools. Although a sedentary job is defined as one which involves sitting, a certain amount of walking and standing is often *213necessary in carrying out job duties. Jobs are sedentary if walking and standing are required occasionally and other sedentary criteria are met.
(b) Light work. Light work involves lifting no more than 20 pounds at a time with frequent lifting or carrying of objects weighing up to 10 pounds. Even though the weight lifted may be very little, a job is in this category when it requires a good deal of walking or standing, or when it involves sitting most of the time with some pushing and pulling of arm or leg controls. To be considered capable of performing a full or wide range of light work, you must have the ability to do substantially all of these activities. If someone can do light work, we determine that he or she can also do sedentary work, unless there are additional limiting factors such as loss of fine dexterity or inability to sit for long periods of time.
(c) Medium work. Medium work involves lifting no more than 50 pounds at a time with frequent lifting or carrying of objects weighing up to 25 pounds. If someone can do medium work, we determine that he or she can do sedentary and light work.
20 C.F.R. § 416.967.

. Protective filing is a term for the first time an individual contacts the Social Security Administration to file a claim for benefits. A protective filing date allows an individual to have an earlier application date than the date the application is actually signed.

. Under the Local Rules of Court "[a] civil action brought to review a decision of the Social Security Administration denying a claim for social security disability benefits” is "adjudicated as an appeal.” M.D.Pa. Local Rule 83.40.1.

. If the claimant is engaging in substantial gainful activity, the claimant is not disabled and the sequential evaluation proceeds no further. Substantial gainful activity is work that "involves doing significant and productive physical or mental duties” and "is done (or intended) for pay or profit.” 20 C.F.R. § 416.910.

. The determination of whether a claimant has any severe impairments, at step two of the sequential evaluation process, is a threshold test. 20 C.F.R. § 416.920(c). If a claimant has no impairment or combination of impairments which significantly limits the claimant’s physical or mental abilities to perform basic work activities, the claimant is "not disabled” and the evaluation process ends at step two. Id. If a claimant has any severe impairments, the evaluation process continues. 20 C.F.R. § 416.920(d)-(g). Furthermore, all medically determinable impairments, severe and non-severe, are considered in the subsequent steps of the sequential evaluation process. 20 C.F.R. §§ 416.923 and 416.945(a)(2).

.If the claimant has an impairment or combination of impairments that meets or equals a listed impairment, the claimant is disabled. If the claimant does not have an impairment or combination of impairments that meets or equals a listed impairment, the sequential evaluation process proceeds to the next step. 20 C.F.R. § 404.1525 explains that the listing of impairments "describes for each of the major body systems impairments that [are] considered] to be severe enough to prevent an individual from doing any gainful activity, regardless of his or her age, education, or work experience.” Section 404.1525 also explains that if an impairment does not meet or medically equal the criteria of a listing an applicant for benefits may still be found disabled at a later step in the sequential evaluation process.

. The GAF score allows a clinician to indicate his judgment of a person's overall psychological, social and occupational functioning, in order to assess the person's mental health illness. Diagnostic and Statistical Manual of Mental Disorders 3-32 (4th ed. 1994). A GAF score is set within a particular range if either the symptom severity or the level of functioning falls within that range. Id. The score is useful in planning treatment and predicting outcomes. Id. A GAF score of 41-50 indicates serious symptoms or any serious impairment in social, occupational or school functioning. Id. A GAF score of 51 to 60 represents moderate symptoms or any moderate difficulty in social, occupational, or school functioning. Id. A GAF score of 61 to 70 represents some mild symptoms or some difficulty in social, occupational, or school functioning, but generally functioning pretty well with some meaningful interpersonal relationships. Id. A GAF score of 71 to 80 represents transient symptoms, if present, and ex-pectable reactions to psychosocial stressors or *217no more than slight impairment in social, occupational, or school functioning.
