2025Administrative wage records

Assessment of the Strong Workforce Program

California Legislative Analyst’s Office

Kept because it argues against the case. Earnings improved for CTE students — and at similar rates for everyone else, which the analyst reads as the labour market rather than the programme.

2021Selection on observables

Career Technical Education and Labor Market Outcomes: Evidence from California Community Colleges

Stevens, Kurlaender & Grosz — Journal of Human Resources; NBER working paper

2010Federal evidence review

What Works Clearinghouse Intervention Report: AVID

Institute of Education Sciences, U.S. Department of Education

The federal review. Of 66 studies of AVID it examined, one met its evidence standards with reservations — a quasi-experimental study of 96 students in a single Colorado district, which reported too little for an effect size to be computed. Scoped to adolescent literacy, so it is a statement about the research base rather than about AVID’s college claims.

1998Background papers

The Quality of Vocational Education (National Assessment of Vocational Education background papers)

Adam Gamoran (ed.), including Rasinski & Pedlow — U.S. Department of Education

The origin of the “8 to 10 times less likely to drop out” claim, at volume p.182 — and the page after it, where the authors call the comparison a transcript-classification artefact and redo the analysis, getting about a 12 percent reduction instead.

Grouped by what a document can support, not by how much we like it. Only the first group can carry a claim that the academy caused anything; the counts are the ones most often quoted at us, and they cannot.

One we cannot host

The California Department of Education’s “CTE facts for school leaders” page carries ten statistics and no citations. We checked its archived versions back to February 2015: the same ten claims, uncited, for eleven years. Two of them we traced ourselves to the 2009-10 Profile above. It is a live page rather than a document, so there is nothing to keep a copy of.
