A formative evaluation can be defined as parts to whole. In comparison a summative evaluation can be defined as a summary of the whole. Formative evaluations are conducted several times over the course of the school year and is used to improve overall teacher quality. 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.
