What researchers studied

National institutional panel using difference-in-differences and staggered-adoption event studies to compare two-year colleges before and after states added STEM awards to performance-based funding formulas. A national panel assembled from 691 two-year institutions, with an analytic sample of 8,266 institution-year records from 639 institutions between 1997 and 2020

What they found

  • The main difference-in-differences models did not detect an increase in total STEM awards or a broad shift in awards after states introduced STEM incentives.
  • Event-study estimates suggested medium-term STEM credentials rose 2 to 3 percent in the first two years and 4 percent by year five, while longer-term awards followed an opposing trajectory. Total STEM awards did not show a sustained increase.
  • For minoritized students, longer-term STEM awards declined while shorter-term awards increased in some event-study estimates. The evidence was noisy and does not establish that institutions deliberately tracked individual students.

What the study does not prove

  • The estimates were suggestive rather than causal because staggered treatment left limited post-policy follow-up and a small effective comparison sample.
  • Event-study confidence intervals were wide, and the primary difference-in-differences estimates were largely null.
  • The data measured credentials awarded at the institution level, not individual advising, program entry, completion pathways, earnings, or student choices.
  • The study could not determine whether increases reflected newly created programs or more awards within existing programs, and the data ended in 2020.

Evidence strength: Long national panel with multiple quasi-experimental specifications; mixed, noisy estimates and limited post-policy observations make the credential-composition pattern suggestive.

Why this matters for families

Before choosing a STEM credential, ask about duration, transferability, the next credential in the sequence, course requirements, and the student's preparation for the mathematics and science ahead.

Noor interpretation

How Noor translates the evidence into practice

A STEM label does not tell a family how long the pathway is, what it leads to, whether credits transfer, or which mathematics and science prerequisites the student must master.

Noor Lyra helps learners connect an academic goal to the actual course sequence, prerequisite skills, workload, and evidence of readiness required to progress through it.

No single study determines a student's plan. Noor uses research as one input alongside the learner's goals, observed performance, academic context, and response to instruction.
