This study aimed to find a valid and reliable self-assessment procedure and instrument to measure the spiritual and social attitude domain of Belief and Morality (Aqidah Akhlak) subject in Madrasah Tsanawiyah by implementing Borg & Gall's research and development model. The instruments' content validity was analyzed using the Aiken formula, and the construct validity used Explanatory Factor Analysis (EFA), while the instrument reliability was conducted by using Alpha Cronbach. The results showed that the instrument's content validity and construct validity were valid. In addition, there was a positive relationship between morality to Allah and the Messenger of Allah towards the morality of parents, teachers, themselves, and others. The 2013 curriculum demands diverse evaluation instruments to measure affective, cognitive, and psychomotor learning outcomes comprehensively. The instruments developed in this study are expected to be used as a reference for teachers in developing instruments to evaluate learning outcomes in the domain of attitude (affective), both spiritual and social attitudes. The instruments can measure the achievement of learning outcomes regarding the affective domain in Madrasah Tsanawiyah or the equivalent.
