The NASDTEC Interstate Agreement, and the cycle turnover that made older guides stale
The current cycle is 2025–2030. Any guide relying on the 2020–2025 signatory list is describing an expired agreement — which is a cheap way to date a source that looks authoritative.
NASDTEC's own description of what its agreement is not
It is not a collection of 2-way agreements of reciprocal acceptance.
It is not a guarantee that all certificate titles will be accepted by a receiving state.
It is not necessarily "full" reciprocity.NASDTEC, NASDTEC Interstate Agreement — read 9 September 2026

Public and gated
The boundary is sharper than most descriptions suggest, and it matters for how anyone should build on this source.

Gated: The NASDTEC KnowledgeBase — the per-jurisdiction requirement detail — sits behind member sign-in.
Our policy. This site cites state rules directly for every requirement. NASDTEC is cited only for the agreement's own scope language, which is public. The gated KnowledgeBase is never used.
What we could not establish
How this differs from the compact
The NASDTEC Interstate Agreement is a set of one-way statements by each jurisdiction about which other jurisdictions' certificates it will accept, and it has operated for decades. The Interstate Teacher Mobility Compact is a newer interstate compact intended to replace much of that with a commission-administered process — and it is operating unevenly — live in Pennsylvania, absent from Colorado’s guidance. Neither one, on its own, tells you what a specific state will require of you; that is in the state's own rules, which is what our corridor pages read.
