FWIW and anyone interested. I just completed Gleim's FIRC which has been updated. Much improved. I tried AOPA's 2 years ago and it was good also. All of them probably are. Here's my review comments: Dear Mark, Thank you for taking the time to write us with your impressions of Gleim's Flight Instructor Refresher Course (FIRC). Believe me when I say we do not take praise casually. Your satisfaction is our goal.

Sirinity Zimmermann, ACR/AGI/IGI Name: Mark xxxxxxxx Time Spent: Excellent Amount Learned: Excellent Chance to repurchase: Good Chance to recommend: Good Overall rating: Excellent I have used Gleim's FIRC numerous times, and this version is very good and an improvement over the previous versions. I especially liked the references (links) that one just clicks on to find additional information and/or to enhance knowledge of various topics. I have added many of these to a folder for my CFI activities and reference. The course is a good overview of what a CFI should have knowledge of and what to teach. The course, I believe, encourages areas a CFI should study that they are perhaps weak or require refreshing in, such as the links for faasafety.gov courses. I plan are hitting a few of these myself. Overall, a very good course that CFIs will learn what they should be teaching, where to find additional information for the student as well as a CFI, and the invaluable reference links provided in the course. I enjoyed the course, learned a few new (and old) things, recognized areas I need further study in myself, and would gladly recommend the FIRC to other CFIs. Thank you.
