Which type of laboratory units are excluded from being categorized as instructional laboratories?

The correct answer identifies units used for research beyond undergraduate education as excluded from being categorized as instructional laboratories. Instructional laboratories are primarily designed to provide hands-on learning experiences related to a course of study, typically at the undergraduate level. When a laboratory unit is dedicated to advanced research activities, it often implicates a focus on independent projects and specialized research efforts that are not primarily aimed at instructional purposes for undergraduate students.

This distinction is crucial because instructional laboratories emphasize education and skill development in a structured setting, while research facilities cater to advanced scholarly pursuits aimed at contributing new knowledge in a particular field. Therefore, units focusing on research beyond the undergraduate level do not align with the primary function of instructional laboratories.
