Judging teachers partly by their students' test results generally makes schools better. 0.50 Agree Disagree
If you disagree, this page has a column for you. A study, record or dataset for “Without a measure of results, teacher ratings rest on a principal's impression, and nearly everyone ends up rated the same”, which rests on argument alone.

Each reason is a claim with its own page. Score = sign x (2 x Truth - 1) x Conf x Link x Imp x Uniq, and every column is here so the row can be multiplied out and checked. A reason argued false scores negative and counts against the side it is filed on; a reason nobody has argued yet scores exactly 0, and so does one whose own page has no work behind it.
What Would Change the AnswerTruth scores →
Every claim beneath this page held at false and then at true, one at a time, with the whole graph recomputed each time. "If false" and "if true" are where this page’s truth score lands; "Move" is how far apart they are. "If settled" is that same distance with the input’s confidence held at 1, which is what it would be worth once the work behind it is finished, so the gap between Move and If settled is the value of doing that work. This is one input at a time and finds single points of failure; it does not test several inputs moving together, which is how correlated assumptions actually fail.

What this page needs right now
| # | The gap | Where it goes | Who is best placed to fill it |
|---|---|---|---|
| 1 | A study, record or dataset for “Without a measure of results, teacher ratings rest on a principal's impression, and nearly everyone ends up rated the same”, which rests on argument alone | Evidence Ledger | anyone with the source |
| 2 | A measurement both sides would accept in advance, with the reading each side predicts | Objective Criteria | anyone who can name a yardstick the other side would sign |
Named gaps, read off the tables above, so a newcomer can see exactly where a contribution goes. None of them requires agreeing with the page, and each one links to the form it goes in.

- Coverage
- Of 6 scored rows, 6 have no linkage page, 6 have no importance page, 6 have no uniqueness page. This page reads 6 other pages. 6 of them are one-sided or empty: Without a measure of results, teacher ratings rest on a principal's impression, and nearly everyone ends up rated the same.; Parents deserve to know whether their child's teacher is helping students learn, and test growth is the one measure that can be compared across classrooms.; Teachers who consistently help students grow deserve recognition and pay that a system without measurement cannot give them.; Students arrive with wildly different home lives and prior learning, and a single year's scores cannot cleanly separate the teacher's effect from everything else.; When jobs depend on scores, teaching narrows to what is tested, and subjects, projects and habits that are not tested get pushed aside.; Strong teachers avoid the hardest schools and classes when a low score can cost them their job, which hurts exactly the students who need them most..
- Bottom line
- The disagreement turns on whether test results measure what a teacher actually adds or mostly reflect which students walked in the door.
Structural Checks
| Finding | How serious | What it means |
|---|---|---|
| Nothing stated would show it false | a note | No testable prediction is listed, so as written there is no observation that would count against this belief. |
Faults the shape of the argument can show without reading a word of it: a claim used to support itself, a conclusion listed among its own premises, the same page counted twice. None of these changes a score. The wiki also specifies pattern-matching the prose for ten named fallacies; that is deliberately not done here, because a matcher looking for “attacking the person rather than the argument” would fire on the central legitimate argument on this whole site, and a score moved by a regular expression has no page to appeal to.

Idea Stock Exchange, belief page judging-teachers-partly-students, truth 0.50, confidence 32%, revision 42c8344 of 2026-10-04. The revision is what makes this quotable: these numbers move as the argument is worked on, and rebuilding that revision reproduces them exactly.
Every number on this page as data: judging-teachers-partly-students.json. Constants: K = 1 · UNARG = 0.5 · DEFLINK = 1 · DEFIMP = 0.5 · DEFUNIQ = 1. A reason placed under a conclusion is presumed relevant until a linkage page says otherwise; the burden is on the challenger. The neutral start for importance, the wiki's own rule.
Every value here is computed from the tables above at build time. Nothing is typed.
