25 years, ASDEC master instructors have been delivering accredited clinical training in reading, writing, handwriting, spelling and math. We offer pathways to practice to hundreds of teachers every year pre-k through high school. ASDEC faculty are all Certified Academic Language Therapists who have also been trained in a wide array of specialized reading programs such as Orton-Gillingham, Sounds In Syllables, Alphabetic Phonics and Wilson Reading System.  Drawing upon years of experience as therapists and trainers, our faculty develops and delivers  multisensory training programs to educators and parents in the Washington, DC region as well as throughout the country and overseas.

 

ASDEC is the only IMSLEC-Accredited training center that delivers certification pathways in reading and in Math.  ASDEC Math Director, Marilyn Zecher has been named the first (and only) Honorary Math Fellow/ of the Academy of Orton-Gillingham Practitioners and Educators.

 

Our Master Instructors design and deliver evidence-based science of learning principles of structured multsensory methods designed to accelerate learning for all students but is essential for those with learning disabilities.  ASDEC methods build on aligned multi-tiered systems of support that enable classroom teachers, para-educators, special educators and volunteers to learn diagnostic and prescriptive methods that build mastery and automaticity in reading, writing and mathematics. These highly effective practices train educators to deliver multi-part lesson plans interwoven with opportunities for individual and group practice.

 

Trinity University Washington recognizes all ASDEC courses as meeting their rigorous standards for graduate level training.

“ASDEC’s courses have been stimulating, edifying, and above all energizing. Language I and the Practicum gave me a powerful approach to teaching reading and writing as well as a more comprehensive understanding of the English language and language disorders. I have become a better parent and teacher, and a stronger advocate for my children and my students as a result."
