Thank you all for your feedback. You've confirmed for me that I'm not missing some obvious reason for their Gifted approach.

My approach now is to a) formally discuss this with the gifted teacher, prior to b) taking this up with the Principal, prior to c) taking up with the school board. I will ask them to articulate the specific benefits behind the rotating approach to at least see if there was any real strategy behind this method. Assuming there is not any strategy behind this approach (other than "we just wanted to expose them to a number of different areas of gifted learning") then I will spell out the "decelerated" learning component of this flawed strategy & hopefully get them to see the flaws in their approach.

I actually DO hope that they have some other defensible rationale for this approach - - otherwise I fear that we have people who would likely not qualify for a gifted program making decisions about how such a program is configred.

Thanks again for the feedback.
