A systematic random sample assigns students to a sampled school's assessment sessions from a list of grade-eligible students provided by the school. The school also keeps track of students that miss the assessment sessions, conducting makeup sessions if needed.

For student sample selection, each school sends a student listing form (SLF), a complete list of its fourth- or eighth-grade students, to a designated sampler. A school's form must include all grade-eligible students, although not in any particular order. The sampler enters the number of students listed on the school's student listing form and other necessary information into a sampling algorithm program. The program generates a random start number, calculates the skip pattern, and systematically selects 30 sample line numbers for each session.

To compensate for new enrollees not listed on the student listing form, the sampling algorithm program also generates extra line numbers for a supplemental sample of new students.

School administrators review student samples and identify students incapable of taking an assessment because of either disability (SD) or limited English proficiency (LEP). These inclusion criteria were revised in 1996 to communicate more clearly a presumption of inclusion except under special circumstances, thereby allowing more SD or LEP students into the assessment.

After an assessment session, each school makes a count of the non-excluded students who did not attend the session. If this count exceeds three students, the school conducts a makeup session for all students absent from the initial session.
