Admittedly, this is possibly not of general interest, but I suspect that a few of my regular readers will find it of interest:
Rick Hess is out of town; while he's away, his column is being guest-written by Melissa Junge and Sheara Krvaric, who are lawyers at the Federal Education Group. They're writing on federal education funding. If "supplement/supplant" and "time and effort" are familiar terms to you, you may find it of interest. Their first entry is on compliance, the next on supplement/supplant, next on time and effort, and today on implementation (particularly around cooperation with private schools).
