"A recipe for the SATs. Add a heap of terrified children to a pan of boiling pressure. Add difficult but not impossible questions, with one well-qualified teacher. Add 101 worries, while kneading in a big enough classroom, with necessary tables and chairs, along with all required equipment. Stir until complete. Mixture will have changed into, hopefully, a lot of smiles!" Until it gets to the heads and governors, that is - but that's a completely different story.
