Massachusetts Comprehensive Assessment System

What Is the MCAS Alternate Assessment?


The Massachusetts Comprehensive Assessment System (MCAS) is the Commonwealth's statewide assessment program developed in response to the Education Reform Act of 1993. MCAS, along with other components of education reform, is designed to strengthen public education in Massachusetts and ensure that all students participate in a challenging curriculum based on the Massachusetts Curriculum Frameworks.

All students educated with Massachusetts public funds, including students with disabilities, must participate in MCAS using one of the following formats:

  • Routine (standard) MCAS testing
  • MCAS testing using one or more test accommodation(s)
  • MCAS Alternate Assessment (MCAS-Alt)

Students with disabilities take standard computer-based or paper and pencil MCAS tests, either with or without accommodations, at the grade specified for assessment in that subject. A very small number of students with the most significant disabilities, about 1% statewide, take the MCAS Alternate Assessment.

Each student's IEP or 504 team decides how, not whether, the student will participate in MCAS in the coming year. Guidelines used by IEP Teams to make these decisions can be found in the Department publication, Principal's Manual for MCAS-Alt Download Word Document which is updated annually.

The MCAS-Alt consists of a portfolio of materials collected annually by the teacher and student. Evidence for the student portfolio may include work samples, instructional data, videotapes, and other supporting information and materials based on the student's performance in the subject being assessed.
