The Montana Office of Public Instruction (OPI) Assessment Unit supports teaching and learning in Montana’s accredited schools through the Montana Comprehensive Assessment System (MontCAS), which includes a suite of required state assessments aligned to Montana’s academic content standards. Data literacy and its direct influence in guiding instruction, alongside a balanced approach including the use of formative and interim strategies ensures all children have fair and equitable opportunities to obtain a high-quality education and reach, at a minimum, proficiency on challenging academic content standards. The Assessment Unit is organized under the leadership of Chief Program Officer Tracy Moseman in Education Services Division within the Teaching and Learning Department. The Teaching and Learning Department is led by Senior Manager Colet Bartow.
