Irlen in schools

From Irlen.wiki, an independent record of the Irlen Institute, its colored overlays and filters, and what researchers say

Researched and compiled by the Irlen Wiki editorial team · First published · Revised

In brief: Many Irlen screeners are teachers and the Institute says its overlays are used in more than 4,000 school districts; ophthalmologists and reading specialists have opposed school screening, including a 2015 Maine bill.[2][8][7]

A note on independence: Irlen.wiki is an independent record compiled from irlen.com, irlensyndrome.org, public records and published research.

How Irlen reaches schools

Schools are central to the Irlen network. Many certified screeners are teachers, and the Institute says many school districts include Irlen screening in their regular test battery and that its overlays are used by more than 4,000 school districts.[1][2] The training workshop is open to anyone with a teaching certificate.[3]

What schools say, according to the Institute

The Institute publishes a page of quotations from school staff. One says the Santa Maria-Bonita School District in California trained 15 intervention teachers as screeners; a Kansas superintendent calls the method an essential component of a reading support program; a literacy program says about 40% of its learners have moderate to severe Irlen Syndrome.[4] These are testimonials selected by the Institute, not evaluations.

The foundation’s school work

The Irlen Syndrome Foundation publishes toolkits for parents and educators and raises money for what it calls Irlen Pilot Schools, as well as scholarships. During Irlen Syndrome Awareness Week it encourages students to give classroom presentations and schools to turn out the lights.[5][6]

Controversy in Australia

In June 2019 ABC News reported that Irlen information and practitioners were reaching Western Australian schools: a primary school in Kalgoorlie advertised a visit by an Irlen clinic, and an Irlen diagnostician ran an after-hours session that she said 17 teachers attended. The state education department said the session was informal and that schools choose their own training.[7] Reading researcher Anne Castles told ABC that schools should be driven by the best evidence and that the evidence shows Irlen treatment is not effective; the Dyslexia-SPELD Foundation WA warned it can take students away from interventions that work.[7]

Legislation in Maine

According to the American Academy of Ophthalmology’s EyeWiki, in April 2015 ophthalmologists in Maine stopped a bill that would have created a pilot program to screen elementary school pupils for Irlen syndrome.[8]

Professional guidance for schools

The joint statement on learning disabilities advises early referral to qualified educational professionals for evidence-based evaluation and teaching that explicitly covers phonemic awareness and phonics, and says colored lenses and filters are not supported.[9] RANZCO’s statement is aimed at educators as well as clinicians and recommends language-based reading interventions.[10] See Irlen and dyslexia.

Common questions

Do schools use Irlen screening?

Some do; the Institute says many districts include it and that more than 4,000 districts use its overlays.

Why is Irlen in schools controversial?

Ophthalmologists and reading specialists say it lacks evidence and can delay effective reading help.

Did any U.S. state consider Irlen screening in schools?

Yes. EyeWiki says ophthalmologists stopped a Maine pilot screening bill in 2015.
