LIEPs can be designed in many ways depending on local needs. PDE does not prescribe program design methodology or approaches to implementation. Also, “best practice” is situational. The best approach in one district may be less than optimal in another, even with seemingly similar demographics. PDE has produced a document that districts can use to help evaluate the comprehensiveness of their approach to program design, though. You can find this document on the LIEP page of the PDE EL website.
