Which type of test would best assess a student's performance in relation to set educational standards?

A criterion-referenced test is specifically designed to measure a student's performance against a predefined set of standards or benchmarks. This type of assessment allows educators to determine whether a student has achieved a specified level of understanding or skill in a particular area, such as proficiency in language or communication.

By focusing on specific skills and outcomes as defined by educational standards, criterion-referenced tests provide valuable insights into a student's competencies in relation to the objectives of a curriculum. This enables educators to tailor instruction to meet students' individual needs and track their progress over time.

In contrast, the other types of tests serve different purposes. Norm-referenced tests compare a student's performance to that of a larger group, which might not reflect mastery of specific educational standards. Standardized tests can include both norm-referenced and criterion-referenced components, but they do not exclusively focus on assessing against predetermined standards. Diagnostic tests are often used to identify specific learning needs and areas of difficulty, rather than to evaluate overall performance in relation to educational standards.
