The document discusses different types of tests, their purposes, and characteristics. It describes screening, placement, proficiency, aptitude, diagnostic, achievement, and progress tests. Direct and indirect tests as well as discrete point and integrative tests are also defined. Guidelines for developing effective tests are provided, including moderating tasks, determining an appropriate level of difficulty, ensuring discrimination among learners, using a representative sample, avoiding overlap, providing clear instructions, considering timing, and avoiding bias in the layout. Moderation of marking schemes, standardization of examiners, and follow-up reviews are also recommended to help ensure tests achieve their intended purposes.
