Do EIW and EIL correlate with the student's chronological grade level?

Each level of EIW and EIL was developed to include instruction covering the skills one would typically expect a student to learn at that corresponding grade level. Due to our method of reteaching concepts learned at previous levels and our spiral approach to curriculum, along with modeling of all skills, most students are able to jump right into their EIW or EIL curriculum at grade level with success.
