Which of the following is an example of an informal assessment?

Portfolio assessment serves as an example of an informal assessment because it emphasizes the collection and evaluation of a student’s work over time to demonstrate learning, skills, and growth. This type of assessment is typically unstructured, allowing educators to observe student performance in a variety of contexts, such as classwork, projects, and reflections. By reviewing a portfolio, teachers can gain insights into a student’s learning process, strengths, and areas that may require further support, rather than adhering to rigid testing criteria found in formal assessments.

In contrast, standardized academic tests and computer-based adaptive tests are formal assessments that follow set guidelines and scoring procedures to measure student performance against established benchmarks. A comprehensive evaluation represents a more formal process that typically involves a variety of standardized tools and methods to assess a student’s educational needs comprehensively. These assessments usually require strict adherence to standardized protocols and provide quantitative data rather than qualitative insights into a student's learning journey.
