The State Board of Education has approved a new statewide standard for the test-based portion of teacher evaluations.
State law requires that teachers are evaluated each year. That evaluation must include how well that teacher’s students performed on standardized exams — and whether they did better or worse than expected, based on a complex statistical formula.
That formula is known as VAM, or value-added model. The VAM score counts for at least one-third of a teacher’s total evaluation score.
