Passed the IDA certification exam — took me 14 months of prep and it was worth it
I finally have my IDA Certified Dyslexia Practitioner credential and I need to share what getting here actually looked like because most posts I've seen make it sound more linear than it is. I'm a reading specialist with 6 years of classroom experience, and it still took me 14 months from when I started studying to when I passed the exam. The written knowledge exam is genuinely hard and covers a depth of linguistics and reading science that goes well beyond what most teacher prep programs include.
The exam has two parts: a written knowledge exam and a performance assessment where you demonstrate structured literacy instruction. The knowledge exam was the harder piece for me personally. It covers phonology, orthography, morphology, and syntax at a level where you can't just know the terms — you need to be able to apply them to student error analysis. I scored a 74% on my first attempt at the knowledge exam and needed a 70% to pass, so I cleared it but barely.
The content that took me the longest to master was the underlying research base — Orton-Gillingham history, the Simple View of Reading, the reading rope model, and how specific instructional approaches connect to what the neuroscience actually shows. The exam expects you to know why structured literacy works, not just how to deliver it. I spent about 6 months in a study group with three other practitioners which was probably the most useful thing I did.
Cost-wise, the exam fees plus required coursework for eligibility set me back around $2,200 total before I even sat for the test. That's not including study materials. Budget for this one carefully if money's a constraint.
The study group approach is underrated for this exam. Explaining the Simple View of Reading or the four-part processing model to another person and fielding their questions is such a better retention method than reading notes alone. Found my group through a local literacy council and we met every other week for almost a year.
The $2,200 figure is helpful — I was trying to budget for this and couldn't find a realistic all-in estimate anywhere. Did that include the required coursework hours or just the exam and application fees? I'm trying to figure out if I need to do additional coursework before I'm even eligible to sit.
The phonology section depth always surprises people coming from a teaching background rather than a linguistics one. I had to essentially teach myself the International Phonetic Alphabet from scratch because my teacher prep program had never covered it at that level. It's a real lift if it's new to you.
14 months sounds long but honestly that timeline is pretty realistic for someone working full-time. The people I've seen try to rush through it in four or five months either burn out or don't pass the knowledge exam. The content genuinely takes time to internalize especially the research base stuff.
