How are we picking up these kids?

Discrepancy model: Person had to be functioning (in terms of reading, writing, math) at a level significantly lower than their mental ability (IQ) — is the discrepancy significantly large?

For school aged kids (K-12):

PL 94-142 → IDEA → RtI

The first two focused on the discrepancy approach.

A child with a learning disability is not going to show 12 months worth of growth over a 12 month time period. Maybe this looks like only 9 months worth of growth. Or 8 months worth of growth. This doesn't sound like a big difference. But if you multiply this over years, it becomes a widening gap. This gap then gets bigger and bigger as they get older because with each successive year, they get farther and farther behind. Response to Intervention (RtI) was supposed to be the solution. In other words, let’s nip it in the bud!
