Then, the differentiated learning assessment tools were carried out to test in the field, 85 students with special needs from four inclusive schools in West Sumatra, Indonesia. Qualitative analysis was used to develop assessment instruments, while quantitative analysis was used to test instrument validation and measure students' level of involvement with special needs. The results showed that the differentiated learning assessment instrument consisted of four aspects, namely: (1) content, (2) process, (3) product, and (4) learning environment. The validity and reliability of learning assessment instruments are distinguished as being suitable for use with a high level of reliability. Teachers in inclusive schools can assess the readiness, interest, and learning profile of students with special needs.
