Teacher can utilize both assessment for learning and assessment of learning to—

Correct Answer: know children's progress and achievement level

Explanation:

Assessment in an educational context serves dual purposes to support both the ongoing learning process and to evaluate overall outcomes:

1. Assessment for Learning (Formative Assessment): This is an ongoing process that helps teachers and students monitor learning progress during instruction. It provides continuous feedback to identify students' strengths, track their development, and address learning gaps.

2. Assessment of Learning (Summative Assessment): This typically occurs at the end of an instructional unit, term, or academic year. It measures what students have learned and determines their overall achievement level relative to established benchmarks or standards.

By effectively utilizing both assessment for learning and assessment of learning, teachers gain a comprehensive understanding of both the ongoing progress of children and their ultimate achievement level.
