Cohort parameter type is a fixed list of values that Chalk uses for cohort parameter type. The allowed values are PREFERENCE, DIVERSITY, SPREAD, CLUSTER. A record can only ever hold one of these exact values, which keeps cohort parameter type consistent across curriculum, assessment, faculty, scheduling, accreditation, and budget records, as well as the API. When you see one of these on a record, it is one of the defined cohort parameter type states rather than free text, so reports and automations can rely on it.
