The correct choice is formative assessment because this type of evaluation occurs during the learning process, allowing teachers to gather data on student understanding through observation, questions, and informal feedback during classroom activities. Formative assessments are integral to guiding instructional decisions and modifying teaching strategies to better meet the needs of students. They help in identifying what students grasp and what they struggle with in real-time, thus enabling continuous improvement in learning outcomes.

In contrast, summative assessments evaluate student learning at the end of an instructional period, typically through tests and projects to determine if learning objectives have been met. Diagnostic assessments aim to identify students' strengths and weaknesses before instruction begins, helping teachers to tailor their approaches. Standardized assessments are formal evaluations that compare student performance across a larger population, often administered under consistent conditions to gather data on achievement levels.
