A modular learning system for certifying learning applications is provided. When the system receives a request to certify a learning application from a learning application authoring user, the system provides a certifying user an interface to view the learning application and determine whether the learning application meets standards for certification. The certifying user provides a certification for the learning application and the system determines a fee for the certification service. The learning application author pays the fee and a certification is associated with the learning application. A certification badge may also be generated for display with the learning application to indicate compliance of the learning application with the certification standards.
