. Administrators who conduct formative evaluations may pop into the classroom for a limited amount of time with the goal oflooking for specific things such as the ratio the teacher calls on boys vs. girls, classroom management practices, etc. A formative evaluation is much more focused than a summative evaluation. Formative evaluations help build the summative evaluation.
