This researchhad the purpose of developing measurement instruments for mastering pedagogical knowledge based on mentoring. The research method using the stages of instrument development refers to test development procedures according to Oriondo&Dallo-Antonio: (1) test design, (2) test trials, (3) determination of validity, and (4) determination of reliability.The sample used was 120 students in the even semester of 2017/2018 academic year in the university of sanatha dharma and University of ahmad dahlan, of biology education study program.Polytomous data were analyzed using Partial Credit Model using the QUEST program. The results showed that as many as 11 items of PK instruments were proven fit with the PCM model using the lowest boundary range criteria of INFIT MNSQ of 0.77 and the highest limit of 1.30, instrument reliability of 0.9 based on the estimation according to the test was high. Item difficulty index starts from 2.35 to 0.93 which means all items are in good category.The results of data analysis on validation can be concluded that the instrument product was suitable to be used as a measurement of pedagogical knowledge ability of mentoring-based must be prioritized in learning for students of biological education. © Published under licence by IOP Publishing Ltd.
