The Montana Comprehensive Assessment System (MontCAS) supports a balanced approach to student assessment comprised of:

  • Summative Assessments - provide an overall measure of students' educational goals
  • Interim Assessments - benchmark student achievement throughout the year
  • Formative Assessments - give teachers the ability to adjust teaching and learning strategies in the classroom

Test Window



The vision of the Montana Aligned to Standards Through-Year (MAST) Pilot is to implement “through year” assessments across the state that can eventually replace the traditional end-of-year state summative assessments and satisfy federal testing requirements.

Congress mandates that all state's participate in assessments under the National Assessment of Educational Progress (NAEP) to measure student achievement in core subjects.
