This study aims to develop an instrument that has not been developed before: a career awareness instrument aimed at students, especially students at the junior high school level. The development of this instrument is to obtain data on the condition of student career awareness during the Covid-19 pandemic. This research uses a type of design and development research. The selection of respondents in this study used a simple random sampling method involving 745 respondents. The developed instrument emphasizes six aspects to determine student career awareness. The data collection technique was applied in the form of a questionnaire. Later, the data was analyzed using the Winstep version of the Rasch Model application, which presents several elements. The results of the Rasch model analysis show that the Chronbach Alpha value is 0.78 with item quality as indicated by the item reliability value of 1.00 (particular category), and the level of consistency of respondents' answers is 0.81 (good category). Furthermore, 30 items are suitable for developing this instrument, as seen from the results of the Outfit MNSQ scores that meet the requirements of the Rasch model.
