Final answer:
Criterion-referenced assessments are the most suitable for determining if students have met specific learning outcomes, as they measure against defined goals and objectives.
Step-by-step explanation:
The most appropriate type of assessment for a school counselor to use in this scenario is A. Criterion-referenced. This type of standardized test would enable teachers to determine whether students have met the specific goals and objectives that are defined as the learning outcomes. Unlike other types of assessments, criterion-referenced tests measure student performance against a fixed set of predetermined criteria or learning standards, such as those that could be part of a school curriculum. The test results show the specific concepts that students have learned, and whether they have achieved the required level of proficiency in those areas.
