Requiring a fixed 55 percent marks to appear in NET is criterion-referenced evaluation, since performance is judged against a set standard.

Norm-referenced evaluation (option A) ranks a candidate relative to the group, not against a fixed cut-off.

Placement evaluation (option B) assesses aptitude to place a learner in a suitable course, not eligibility by a fixed mark.

Formative assessment (option D) is ongoing feedback during learning, not a one-time eligibility criterion.

Criterion-referenced tests report mastery of defined objectives, while norm-referenced tests report relative standing.
