I do not use any IEW publications in my writing classes; I write and publish my own curriculum. Here are the covers of my handbooks for my three writing levels:
My writing courses are reviewed and approved by IEW every two years when I go through reaccreditation. Over the course of Level 1 and Level 2, all nine IEW units and all style techniques, except for Triple Extensions, are learned and practiced. Triple Extensions are covered in Level 3.
For PREP-1, in addition to my custom handbook, students also receive a copy of Andrew Pudewa’s Linguistic Development through Poetry Memorization. It is the only IEW book used in any of my classes.
