Agreed. I think about the analogy of interchangeable parts and if that might apply to education. Maybe teachers should just teach and assessors should assess. Interchangeable parts made it so equipment could be more efficiently be manufactured. But that didn't preclude there being a lot of different types of equipment. In fact, there's probably more types of equipment because of interchangeable parts. So for education, having an assessor focus on assessments, independent and separate from instruction, might make it so that there could be easier to assess and more types of assessment, so the teacher doesn't have to always do it. And that might help compare results across teachers.

College Board owns SAT, AP, and (essentially) Common Core so there's been a trend to tighter coupling. I like the idea of an AP Test that anyone can and be assessed separate from the teacher. Same for SAT. I think we need more of that model, not less.

I don't see the advantage of tying assessments to singular institutions especially ones structured like College Board. What this promotes a bottleneck of what can be communicated to others meaningfully. Currently the SAT can be broadly communicated (because CB and others have invested very large amounts of resources into it) and so students optimize for it. Instead they could be putting their efforts to towards learning that is more personally and socially valuable.

I don't think this is just because the SATs are bad tests but fundamentally emerges from the institutional single source of truth model, where the incentive is for the institution to make their test as general/broad as possible and the most broadly accepted , as to capture the most students and hence fees.

I agree that we need more and better assessment - but I don't understand why we would allow a private body to do what should be a utility function of our educational system. Currently, the College Board is able to fill this niche (at great cost) due to a lack of trust in the assessments of individual instructors. Rather than further increasing the cost of assessment by expanding the use of private arbiters, we should seek to make the assessments that are already taking place (in far greater number and scope) more reliable and trustworthy.

I believe this would take the form of a dedicated assessment tool that allows teachers to create individualized assessments JIT based on - or in concert with - their planning and performance workflow. If I'm teaching a structured lesson on polynomials, I should be able to create a valid assessment simply be requesting that one is made. My students should be able to take that assessment on the spot and the results should be immediately available.

I will take assessments with 80% confidence of validity 10x/week over assessments with 100% validity once per year every. single. time.

There's more to be said here - but that's the gist.

Why not have multiple assessors? Let people/parents/whoever pick who they want. Some schools use ACT and others SAT. Having a single assessor seems suboptimal. Alternatives tend to keep things more in check.
