2013, and she is not entitled to Supplemental Security Income under Title XVI of the Social Security Act as an adult . We have jurisdiction under 28 U.S.C. § 1291

. Reviewing the district court’s decision de novo and the determination of the administrative law judge (“ALJ ” ) for substa ntial evidence, Dale v. Colvin , 823 F.3d 941, 943 (9th Cir. 2016), we reverse and remand. Pryor contends that the ALJ erred at step three of the sequential evaluation

process , see 20 C.F.R. § 404.1520(a) (4) , by determining that Pryor does not meet Listing 12.05(C). To meet Listing 12.05(C), a claimant must demonstrate “ (1) subaverage intellectual functioning with deficits in adaptive functioning initially manifested before age 22; (2) a valid IQ score of 60 to 70; and (3) a physical or other mental impairment imposing an additional and significant work

- related limitation. ” Kennedy v. Colvin , 738 F.3d 1172, 117 4 (9th Cir. 2013) (citing 20 C.F.R. p t. 404,

s ubpt. P, a pp. 1, § 12.05)

. The Commissioner concedes, a nd we agree, that the ALJ
erred in its determination that Pryor “does not have a valid verbal, performance or full scale IQ of 60 through 70 and a physical or other mental impairment imposing an additional and significant work

- related limitation of functio n
. ” For example , the only IQ test results in the record report a full scale IQ of 70, and the ALJ gave that examining physician’s report “considerable weight.” The Commissioner contends that this error is harmless because Pryor was also required, but failed, to demonstrate the existence of deficits in adaptive functioning3 18

initially manifesting before age 22. Although we will not reverse on account of an
error th at is harmless, Molina v. Astrue , 674 F.3d 1104, 1111 (9th Cir. 2012) , our review is limited to “only the reasons provided by the ALJ in the disability determination[,] and [we] may not affirm the ALJ on a ground upon which he did not rely,” Orn v. Astrue , 495 F.3d 625, 630 (9th Cir. 2007). The ALJ did not analyze whether Pryor demonstrate d deficits in adaptive functioning manifesting before age 22. Therefore, the ALJ’s error regarding the remaining Listing 12.05(C) criteria requires remand. See Brown

- Hu nter v. Colvin , 806 F.3d 487, 492 (9th Cir. 2015) (“Because we cannot engage in such substitution or speculation, such error will usually not be harmless.”).

W e remand to the district court to further remand to the agency for proceedings consistent with t his disposition . Because we remand for reconsideration at step three of the sequential evaluation process , we do not reach the other
arguments. See Marcia v. Sullivan , 900 F.2d 172, 177 n. 6 (9th Cir. 1990).
REVERS ED AND REMANDED.
