I have worked with various schools. Some have all the curriculum, and materials, schedules, lab material all prepared for a the courses and centers that deliver them. In others, nothing is done, and complete lattitude is given to the instructor to prepare his/her class/course the way the see fit. Personally, having been various postions between both extremes, I prefer to have it all laid out. This way I can focus on delivery, and elaboration if required. Having said this, if the logistics and/or materials are not what I consider quality, it's good to be able to make ajustments, in order to have the right balance of quality, logistics, and still have time to teach.
