Screening, diagnostic, progress monitoring, and outcome assessments are used at different stages to evaluate students' reading abilities. Screening assessments are quick tests given to all students to identify those who may need extra help. Diagnostic assessments pinpoint specific areas of weakness to guide intervention. Progress monitoring checks if students are benefiting from intervention. Outcome assessments determine if adequate yearly progress is being made. Examples of assessments discussed include word lists, oral reading fluency tests, running records, and vocabulary flashcards.
