The ISTQB Model-Based Tester certification is a specialist module at the Foundation Level. A person with the CTFL-Model-Based Tester Certificate has extended the broad understanding of testing acquired at the Foundation Level to enable capabilities required for the Model-Based Testing (MBT) process, methodology and techniques. 

Model-Based Testing is an advanced test approach using models for testing. It extends and supports classic test design techniques such as equivalence partitioning, boundary value analysis, decision table testing, state transition testing, and use case testing. The basic idea is to improve the quality and efficiency of the test design and test implementation activities by:

• Designing a comprehensive MBT model, typically using tools, based on project test objectives.
• Providing an MBT model as a test design specification. This model includes a high degree of formal and detailed information that is sufficient to automatically generate the test cases directly from the MBT model.
