Learning evaluation plays a fundamental role in ensuring the quality of educational processes and outcomes. This study aimed to analyze the validity and reliability of test and non-test instruments used to evaluate Biology learning on the human respiratory system at SMA Negeri 3 Parepare. The instruments analyzed consisted of 20 multiple-choice test items and 20 student attitude questionnaire items. A descriptive quantitative research design was employed. Item validity was examined using the Pearson Product Moment correlation, while instrument reliability was analyzed using Cronbach’s Alpha. The results showed that 15 out of 20 test items (75%) and 17 out of 20 questionnaire items (85%) met the validity criteria. The reliability coefficients were 0.86 for the test instrument and 0.88 for the non-test instrument, both classified as very high. These findings indicate that the instruments are suitable for evaluating Biology learning on the human respiratory system, although several items require revision. Continuous development and periodic testing of evaluation instruments are recommended to maintain the quality of learning assessment.
