Which type of assessments do not adhere to strict rules for administration and scoring?

Informal assessments are designed to gather information about a student's understanding and skills without the constraints of strict rules for administration and scoring. These assessments can take various forms, such as observations, checklists, or informal quizzes, allowing educators to tailor them to individual student needs or contexts. They focus on flexibility and adaptability, making it easier for teachers to assess student progress in a more natural, less high-pressure environment.

In contrast, standardized assessments have specific administration and scoring guidelines to ensure consistency and comparability across different test-takers. Similarly, formal assessments also follow established procedures and usually produce quantifiable data, which means they are much more structured than informal assessments. Experimental assessments, while they may involve less rigid rules than standardized tests, are typically used in research settings and are still bound by certain protocols to test hypotheses in a reliable manner.
