Definition -
Assessments used throughout a lesson or unit that continually monitor and evaluate students’ learning along the duration of the process.
“Formative assessment refers to a wide variety of methods that teachers use to conduct in-process evaluations of student comprehension, learning needs, and academic progress during a lesson, unit, or course. Formative assessments help teachers identify concepts that students are struggling to understand, skills they are having difficulty acquiring, or learning standards they have not yet achieved so that adjustments can be made to lessons, instructional techniques, and academic support.
The general goal of formative assessment is to collect detailed information that can be used to improve instruction and student learning while it’s happening. What makes an assessment “formative” is not the design of a test, technique, or self-evaluation, per se, but the way it is used—i.e., to inform in-process teaching and learning modifications.” (EdGlossary.org)
