The ELCAR, formerly known as the C-PIRK, has been organized around the theory of verbal development. The ELCAR components consist of Screenings, an Achievement Record, and a Verbal Behavior Development Assessment. Curricular repertoires and necessary verbal cups are included to maximize learner and teacher efficiency. The ELCAR package also includes training videos. The ELCAR replaces the C-PIRK and the VBDA (including the pyramids), with nearly every item updated, including:
  New curricular domain categories;
 New repertoires, many of which include specific operants to
be assessed and taught;
 Instructions embedded within the assessment for many items;
New assessment criteria for most items;
 Four different screenings, including a reinforcer screening, observing response screening, verbal operant screening, and instructional readiness screening;
  Indicators for possible missing verbal behavior developmental cusps;
A new list of verbal behavior developmental cusps, protocols, and references;
  New VBDA charts for displaying cusps in the child’s repertoire;
  A materials packet that includes data collection sheets for
many items and screenings within the ELCAR;
  A new updated manual that includes instructions for establishing curricular objectives and mastery criteria and pedagogical considerations for instruction based on cusps present in a child’s repertoire;
 Training videos
