1 Assessment Authoring - Table of Specification (TOS) The Table of Specification (TOS) is a high-level design template for a given assessment. It identifies the claims, components skills, targeted number tasks needed, and the knowledge or skill level desired for each task. Scoping information is also provided, in most cases, and indicates the environment, features and details associated with the specified claims. Assessment design specifications in the TOS allow us to make inferences about what the students can actually do. Because some outcomes are more important than others in making those judgments, each claim is weighted based on course content, required job skills and certification coverage. Using the TOS helps to ensure that assessed tasks are relevant to the environment in which the student will work. In the example below, 25% of the Network Fundamentals Final exam should cover skills from claim For a 50 question exam, approximately 13 tasks should cover skills that support claim Distribution of tasks amongst the component skills is determined during the design phase. Tasks for each claim or component skill can be either declarative, simple procedural or complex procedural depending on the purpose of exam and the type of claim. Claim desired outcome Component Skill supporting skill Desired Claim Coverage
