"In 2001, the instructor training program was seriously weakened by eliminating the prerequisite that instructor candidates pass Road 1, (the 10-hour abridged adult entry-level course) before being accepted into the training program, by making the written test open book and, in some cases, optional and by shortening the instructor seminar. A poorly-qualified Program Director was allowed to rewrite the instructor materials. Some of these problems have recently been rectified after bitter complaints by several long-time instructors."

FYI - In the Road 1 course I took recently, the test was closed book (I got 100%).
