NILD Educational Therapy is Research-Driven and Research-Proven

Research-Driven – Our Practices are Evidence-Based

Research validates NILD educational therapy interventions that have helped students with learning challenges for over 40 years. Every student is unique. NILD’s research-based, individualized approach is unique too.

Hallmarks of NILD Educational Therapy

Teacher’s questions and student discussion are critical components of research-based instruction and “effective teachers… ask students to explain the process they used to answer the questions, to explain how the answer was found.”


Most NILD techniques use a variety of materials because research affirms “simple yet powerful non-linguistic instructional techniques such as graphic organizers, pictures and pictographs, concrete representations, and creating mental images improve learning.”


Basic academic skills and cognitive functions are directly taught to establish the foundation for higher order thinking and reasoning.

“Students need cognitive support to help them learn to solve problems.”  Support comes through explicit instruction of material.


This is a valuable skill as students “generate and test hypotheses.” Moving from specific to general thinking is at the heart of critical thinking.


“Questions help student identify missing information”


“Students access prior experience & knowledge, and are active participants”

–Lyon, Fletcher, Fuchs, Chhabra

Also, “cumulative review guided by questions produces success”.


“Providing frequent and specific feedback related to learning objectives is one of the most effective strategies to increase student achievement.”


Our intervention provides opportunities for students to self-regulate, a skill necessary for any successful learner.

“As students gain competence through systematic and intentional instruction, confidence grows and encourages the transfer of the skills learned to the classroom as well as life.”

I do not think that I know an organization more committed to releasing the potential of all children with learning disabilities than NILD. In the short time that I have gotten to know the members of NILD, I have been very impressed by their knowledge and their desire for keeping abreast of evolving research, particularly in reading intervention. Perhaps more poignantly, however, I have been uplifted by the depth of their dedication to the children. They are a wonderful group.

Research Proven – Our Results are Confirmed Through Data

NILD Research Proven
We aim to unlock an individual’s potential and infinitely expand each student’s horizons. NILD not only has testimonials of academic performance transformed and lives changed, but testing data and the research studies below confirm the transformation we see.




Can NILD’s intensive intervention actually lead to improvements in verbal, nonverbal, and cognitive functioning as evidenced on the WISC IV test?

The WISC IV is a prediction of performance in school, and a measure of a child’s strengths and weaknesses in thinking. NILD Educational Therapists use this data to identify a learning profile, determine a student’s need for therapy, communicate a child’s learning profile to students and parents, and prescribe therapy techniques Although the goal of NILD Educational Therapy® is not to make progress on this particular test, as students progress through NILD Educational Therapy® and thinking skills are inevitably challenged and changed… the results have proven very exciting!

Does NILD Educational Therapy® help students who are below average in reading and written language achievement improve these skills?

Not only did the students demonstrate yearly gains as would be expected within general education alone, their progress exceeded average gains and began to close the achievement gap between them and their peers… representing a significant improvement that allowed them to keep pace with the average achievement of their peers.

Does the completion of an intensive, individualized program of NILD Educational Therapy® affect the achievement scores in reading, spelling, and arithmetic for students with learning disabilities?

Students in this study demonstrated statistically significant gains over time in cognition and achievement on standardized measures.

What was the effect of NILD’s Rx for Discovery Reading intervention on the reading abilities of elementary school students who were below grade level in reading?

Students in this study demonstrated statistically significant gains in the areas of phonemic awareness, phonics, and fluency.

Does NILD’s GET intervention compared with NILD’s IET intervention affect the reading and writing skills of children with reading problems?

The quantitative phase of this mixed-methods study compared the effects of Individual NILD Educational Therapy® (IET) with Group Educational Therapy (GET) on the reading and writing skills of struggling learners. In both settings, NILD Educational Therapy®, mediated by professionally certified therapists, yielded improved reading skills.
