The document discusses the table of specification (TOS), which is a plan prepared by teachers to ensure tests are aligned with content and evenly distributed across topics based on time spent teaching. It describes the objectives of developing a TOS using Bloom's taxonomy, and explains how a TOS helps teachers construct valid assessments that measure learning at different cognitive levels and proportionally assess all topics covered. A TOS also benefits teachers by providing a blueprint for easily creating questions and encouraging mastery of all lesson content.
