Why the secrecy and intrigue over GT?

On the left is a copy of the GT Global Screening data available to MCPS. The screen shot was excerpted from a recent (May 2009)Power Point presentation by Martin Creel to the BOE.

A few months earlier (February 2009), MCPS responded to an MPIA (the State of Maryland version of FOIA) request for data collected in this precise manner, minus student names, etc. Their response, on the right, is self-explanatory.

The MCPS AEI Advisory Committee meets at the direction of the Board of Education. The meetings are open to the public but the documents, voting records, details of the meeting are not available to the public. No, not even the overview of the proposed Gifted policy, which I obtained and made available here.

Is the Advisory Committee Meeting, conducted at the direction of the BOE, immune to the Open Meetings Act? Why isn’t MCPS willing to release the data it has proved is in its possession? Why the secrecy and intrigue?
