What Is the VB-MAPP Generative Learning Assessment (GLA)?

The Generative Learning Assessment (GLA) is a verbal behavior assessment, associated with the VB-MAPP framework, that measures a learner's capacity for generative or emergent language: new, untaught responses that appear once foundational verbal skills are in place. Instead of counting only directly trained targets, the GLA looks at whether language is beginning to expand on its own.

Understanding Language Generativity

Generativity refers to novel verbal responses a learner produces without direct teaching of each one. It shows up as recombinative generalization, emergent relations among verbal operants, and flexible use of previously learned words in new combinations.

Generative repertoires are the goal of verbal behavior programming because they let language grow faster than any one-target-at-a-time teaching plan could achieve.

Using the GLA in Practice

Use the GLA to decide when a learner is ready to shift from intensive tact-by-tact or mand-by-mand teaching toward programming that promotes emergence and recombination. Results help you set goals around generalization, expand multiply controlled verbal behavior, and prioritize teaching procedures, such as matrix training and multiple exemplar instruction, that are designed to produce untaught responses.
