Curriculum-Based Measurement of Reading Growth: Weekly Versus Intermittent Progress Monitoring

We examined the idea that leaner schedules of progress monitoring (PM) can lighten assessment demands without undermining decision-making accuracy. Using curriculum-based measurement of reading, we compared effects on decision accuracy of 5 intermittent PM schedules relative to that of every-week PM. For participating students with high-incidence disabilities—all receiving special education reading instruction ( N = 56)—intermittent schedules of PM performed as well as every-week PM. These findings signal a need for research on the relative accuracy and timeliness of curriculum-based measurement decision making for intermittent and weekly PM.
