Ms. Wipf gives her students a test at the end of each unit to grade them on how well they understand the new concepts. The description above best characterizes which of the following types of assessment?

Diagnostic assessments are conducted before instruction to determine students' prior knowledge and readiness to learn new concepts. Unlike summative assessments, which evaluate learning at the end of a unit, diagnostic assessments help identify learning gaps and inform future teaching strategies. Therefore, Ms. Wipf's tests do not fit this description.

Formative assessments are ongoing evaluations meant to monitor student learning and provide feedback during the learning process. They help educators adjust their teaching methods in real-time. Ms. Wipf's end-of-unit tests summarize learning rather than provide feedback during instruction, making them distinct from formative assessments.

Aptitude assessments measure a student's potential to succeed in a particular area or skill, often predicting future performance rather than evaluating current knowledge. Since Ms. Wipf's tests focus on assessing knowledge after instruction, they do not align with the definition of aptitude assessments.
