In order to identify individual differences of learners in a class, which of the following can be used by a teacher?

To identify individual differences among learners, a teacher can use formative assessments.

Ongoing formative checks reveal how each learner progresses at a different pace and level.

Summative assessments come at the end and grade rather than reveal differences during learning.

Diagnostic assessments locate specific learning difficulties and their causes, a narrower focus.

Peer assessments involve students judging each other, not the teacher mapping differences.

Continuous formative information lets teaching be adapted to individual needs.
