This document summarizes key differences between formative and summative assessment. Formative assessment involves ongoing feedback to improve performance, while summative assessment measures learning at the end of a stage. It also describes four categories of tests (placement, diagnostic, progress/achievement, proficiency), and characteristics of good tests including validity and reliability. The document outlines direct and indirect test items and considerations for writing, marking, and scoring tests, as well as how to prepare students through practice tests and familiarizing them with test formats and skills.
