My district produces that sheet about 2-3 weeks after the meeting where everyone looks at each other and says "yes, we need to evaluate this kid." They then call this the formal consent, not the parent in the meeting saying in the meeting in front of 12 witnesses "I consent to evaluate the child. I've written it down in a letter signed in blood that I'm handing over now." They seem to do this to buy them an extra few weeks to get it all done.
