description: <b>Purpose: </b>The present study assessed the test–retest reliability of the American Sign Language (ASL) version of the Computerized Revised Token Test (CRTT-ASL) and compared the differences and similarities between ASL and English reading by Deaf and hearing users of ASL.<b>Method:</b> Creation of the CRTT-ASL involved filming, editing, and validating CRTT instructions, sentence commands, and scoring. Deaf proficient (DP), hearing nonproficient (HNP), and hearing proficient sign language users completed the CRTT-ASL and the English self-paced, word-by-word reading CRTT (CRTT-Reading-Word Fade [CRTT-R-wf]). Both tests were administered twice, 7–14 days apart, to assess test–retest reliability.<b>Results: </b>Preliminary findings suggested that the CRTT-ASL was acceptably reliable for the DP group across CRTT metrics. All groups showed adequate test–retest reliability for the CRTT-R-wf. The DP group scored comparably across the two language conditions, and on average, the DP group produced significantly lower scores than the two hearing groups on the CRTT-R-wf. The hearing groups did not differ significantly from each other on the CRTT-R-wf.<b>Conclusions:</b> The CRTT-ASL may be reliable for assessing Deaf ASL users, the target population for its use. These findings serve as preliminary support for clinical and research use of the novel CRTT-ASL to assess language processing in Deaf individuals who use ASL. The CRTT-ASL may be sensitive to lexical processing inefficiencies in the Deaf signing population.<b>Supplemental Material S1.</b> Scoring categories of the CRTT.<b>Supplemental Material S2.</b> Example commands from each subtest of the CRTT.<b>Supplemental Material S3. </b>Descriptions of ASL linguistic characteristics for a subset of the CRTT commands.<b>Supplemental Material S4.</b> Deaf proficient (DP) participant hearing and language background information.<b>Supplemental Material S5. </b>A video frame of the signer in the CRTT-ASL.
