Certification Committee

The certification committee of IAALP builds on the work of the International Alliance for Learning (IAL) in the US and the DGSL (Deutsche Gesellschaft für Suggestopädisches Lehren und Lernen) in Germany. In addition to reviewing certification documents at levels 1-3, the committee also offers coaching and mentoring to aspiring Accelerated Learning practitioners at all levels. With the board and the members at large, the committee will also provide focus and direction for the design and development of innovative practices and approaches to instructional design and facilitation.

Certification and quality standards are important, but if they are not constantly revisited and renewed, they simply become standards with mediocre quality. With the help of this community of practice, we intend to continue learning personally and organizationally to provide the best possible guidance and support for Accelerated Learning practitioners everywhere.
