When a student struggles to read, the question isn't whether to intervene — it's which intervention, aimed at which skill. Reading is not one ability but several, and an intervention that targets the wrong layer can run all year without moving the needle. Knowing the landscape of evidence-based reading interventions, and what each one is for, lets you match the approach to the actual breakdown. This is an overview, not a prescription — the specific program should fit your student and your training — but the categories will help you target.
Start by locating the breakdown
Effective intervention begins with diagnosis. Reading rests on a stack of skills, and you need to know which layer is failing:
- Phonological and phonemic awareness — hearing and manipulating sounds in spoken words.
- Phonics and decoding — mapping sounds to letters to read words.
- Fluency — reading connected text accurately and at a reasonable rate.
- Vocabulary and comprehension — understanding the words and the meaning.
A student who can't comprehend because they can't decode needs decoding instruction; comprehension strategies won't help until the words come off the page. Diagnostic data tells you where to aim.
Phonological awareness interventions
For young or significantly delayed readers who can't yet hear and manipulate sounds, intervention targets phonological awareness — rhyming, blending, segmenting, and manipulating phonemes, often without print at first. This is foundational; a student who can't segment the sounds in a spoken word will struggle to map them to letters. Evidence strongly supports explicit, systematic instruction in these skills for at-risk early readers.
