The BLOC battery is made up of four tests designed to assess the language level of children aged from 5 to 14 years. The 580 BLOC items are distributed in four modules (semantics, pragmatics, morphology, and syntax) which are broken down into smaller blocks of ten items. BLOC can provide up to 62 scores regarding both general and specific linguistic skills.
