Which of the following statements is not correct about assessment?

The correct option (the statement that is not correct) is:
"Norm-referenced assessment is useful in diagnostic testing and remedial teaching."

Explanation:

To understand why this statement is incorrect, let us break down the differences between Norm-Referenced Assessment and Criterion-Referenced Assessment:

1. Norm-Referenced Assessment (NRA):
- A norm-referenced assessment compares a student's performance against a national or target group of peers (the "norm" group).
- Its primary purpose is to rank students, determine percentile ranks, or determine where a student stands in comparison to others (e.g., standardized tests like SAT, percentile scoring).
- Because it measures relative performance rather than specific skill mastery or learning difficulties, it is not designed for diagnostic testing or remedial teaching.

2. Criterion-Referenced Assessment (CRA):
- A criterion-referenced assessment evaluates a student's performance against a fixed set of predefined criteria or learning standards (e.g., scoring 80% on a math test).
- It determines whether a student has achieved mastery of specific concepts or skills.
- Because CRA pinpoints specific strengths and weaknesses in a student's knowledge, it is highly useful for diagnostic testing and planning remedial teaching.

Evaluation of Statements:
- "Criterion-referenced assessment is to evaluate the mastery learning of the students." — Correct statement.
- "Criterion-referenced assessment is useful in diagnostic testing and remedial teaching." — Correct statement.
- "Norm-referenced assessment tells us where a student stands as compared to other students in his/her performance." — Correct statement.
- "Norm-referenced assessment is useful in diagnostic testing and remedial teaching." — Incorrect statement (and therefore the right answer to the question asking for the statement that is not correct).
