This research had the main objective to develop a new form/design in the development of test instruments that valid and reliable. The form of the test instrument that was developed adopted the Superitem concept and was integrated into software called Wondershare. Through the integration, digital format test instruments were realized with the structures of the questions' difficulty level which were tiered from the easiest to the hardest stages. The development of these digital test instruments used a quantitative approach to obtain valid and reliable instruments. The stages of development included: 1) determination of the instrument items, 2) test the validity and reliability of instrument items, 3) determination of final instruments as digital test questions, 4) inputting digital test questions into the Wondershare application, 5) trials of the digital test instruments, 6) revision of digital test instruments, and 7) finalization of digital test instruments. The content validation test of instruments involved two education experts, the reliability test of instruments involved 42 respondents, and the trials of digital test instruments based on Wondershare-Superitem involved 12 respondents. Data collection related to content validation test, instrument reliability, and trials of digital test instruments used the instruments in the form of questionnaires. Analysis of the trial results of digital test instruments using analysis techniques of quantitative descriptive by percentage descriptive formula. The results of this research showed the design of digital format test instruments based on the Wondershare-Superitem that are valid and reliable for supporting distance learning implementation of assessment course.
