ASDEC for educators

“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.”

– Graduate of ASDEC Academic Therapy Certification program

What we do

Early Screening and InterventionK-Reading KickStart

ASDEC is the only accredited training program to deliver integrated Orton-Gillingham methods and Montessori strategies designed to identify and teach emerging readers.  Using evidence-based instruction focused on building phonological awareness, oral language development and alphabet skills, we train teachers in the science of reading.

Academic Language Therapy

ASDEC’s Academic Language Therapy Program trains educators in Sounds In Syllables, the most powerful Orton-Gillingham-based approach to teaching reading (decoding, fluency, and comprehension), sound-spelling, and the foundations of syntax and grammar.  Experienced ASDEC faculty deliver in-depth training courses that prepare Academic Language Therapists to work one-to-one with students.

Therapists must complete 200 class hours and 500 practicum teaching hours under the supervision of ASDEC faculty. This supervised teaching enables therapists to apply the lessons learned in their classes to actual teaching sessions with students under the careful guidance of master teachers. This core element of ASDEC’s training program explains why our therapeutic approach is so successful, especially for those students who may have failed to learn under other specialized programs.

Academic Language Practitioner

ASDEC trains classroom teachers and reading specialists to deliver Language Foundations, an evidence-based structured literacy for general education and Tier 2 intervention.  Teachers who complete the 45-hour training course and nine-month practicum are eligible to sit for national certification as Academic Language Practitioners.

Language Foundations (also known as “Structured Language Basics – SLB) is an Orton-Gillingham based multisensory approach to teaching reading-language arts skills in an inclusive classroom.  This curriculum is equally successful with elementary and middle school students for whom reading and spelling present significant problems.  More importantly, the use of Language Foundations in the primary grades can act as a preventative measure for difficulty with reading and spelling in the later grades.

Multisensory Math

ASDEC’s teaching level certification in Multisensory Math is designed for educational professionals working with students in the classroom as well as those who work with students in small groups or one-to-one. ASDEC Math Director, Marilyn Zecher, CALT is a nationally recognized as a leader in applying Orton-Gillingham based methods to her multisensory math instruction.  Her workshops and lectures throughout the country often sell out. Trained in Orton-Gillingham as a classroom teacher in Prince George’s County, MD, Marilyn has a deep understanding of the needs of at-risk students.  Participants at her workshops, courses and lectures are often transformed by her dynamic presentations.

ASDEC Training

The training that I received from ASDEC profoundly and forever changed my philosophy and approach to teaching. (I always half-jokingly say that I want to go back to my pre-ASDEC teacher self, give her a hug, and let her know that she'll one day know how to reach all of the learners in her classroom!) 

In addition to my ASDEC training, however, my instructional knowledge and skills increased further through the time I spent in the classroom with each of you. I consider it such a gift to have taught with you, and I  know this was invaluable to my growth/development as a teacher. Thank you.
