This article describes the development and preliminary psychometric properties of the TeleWrite, a handwriting assessment tool designed to measure the rate, accuracy, and fluency of children's handwriting for children in first through third grade administered via telehealth. A series of three pilot studies were completed to determine initial interrater reliability, content validity, and clinical utility of the TeleWrite. A study with eight children was used to determine preliminary interrater reliability testing using a beta version of the TeleWrite with (n = 9) raters. The reliability coefficient was obtained using intraclass correlation (ICC) and yielded α = 0.92 for total scores, CI [0.815, 0.983] and the Cronbach's α measure for internal consistency was α = 0.95 (excellent). A clinical utility survey of (n = 55) pediatric occupational therapists was used to obtain their clinical impression regarding the usefulness and accuracy. Representing twelve different countries and twenty-two U.S. states, the respondents indicated that 61% (n = 33) are quite or extremely likely to use the TeleWrite in their practice and most participants (64%; n = 35) indicated that TeleWrite was quite/extremely accurate in measuring handwriting performance. Third, a content validity study with nine handwriting experts reviewed and concluded that all ten subtests of the TeleWrite tool are considered essential. All preliminary studies strengthen the development of the TeleWrite assessment to advance to construct validation of the tool.
