Abstract
SENOSTIK is an Android-based application developed in Indonesia to assist teachers in conducting comprehensive diagnostic assessments and planning lessons in alignment with national education policy. Unlike conventional tools that focus on learning outcomes, SENOSTIK is designed to measure student characteristics, strengths, and weaknesses, covering both cognitive abilities and non-cognitive factors. This study evaluates the validity and reliability of SENOSTIK’s assessment instrument, aiming to enhance learning experiences in the digital environment. High school students were selected as respondents to reflect assessment needs across secondary education. Quantitative analysis was applied using Exploratory Factor Analysis (EFA) to examine construct validity and Cronbach's Alpha to test reliability. Results indicate that the instrument demonstrates strong construct validity, meeting established standards, and achieves adequate reliability. Beyond technical contributions, this study highlights the strategic role of valid and reliable diagnostic tools such as SENOSTIK in strengthening evidence-based assessment practices, significantly marking an advancement in educational diagnostic measurement in the digital era.
