Background: Many clients in contact with social services and (mental) health care have mild to borderline intellectual disabilities (MBID). Yet, administering a full intelligence test may not be feasible.

Method: In 318 adults and 305 juveniles, the scores on 14 questions that comprise the screener for intelligence and learning disabilities (SCIL) were analysed in relation to the IQs of the participants.
