ESSA's definition of professional development.
Most federal education law tells you what money can buy. The Every Student Succeeds Act does something rarer with professional development: it tells you what the words mean. The definition is short, it names the thing it excludes, and it has been sitting in the statute since 2015 while most PD budgets kept buying the excluded thing. Here it is in full, one term at a time.
The statute, in full
ESEA §8101(42), as amended by ESSA — the section your Title coordinator cites — defines "professional development" as activities that:
(B) are sustained (not stand-alone, 1-day, or short term workshops), intensive, collaborative, job-embedded, data-driven, and classroom-focused… — ESEA §8101(42), codified at 20 U.S.C. §7801(42)
The definition then lists the kinds of activity professional development may include. The first is activities that "improve and increase teachers' knowledge of the academic subjects they teach, understanding of how students learn, and ability to analyze student work and achievement from multiple sources." The Department's Title II, Part A guidance names coaching, mentoring, and common planning time among the activities that fit. The full list is in the statute; the six words in part (B) are the test every item on it has to pass.
Part (A): strategy, not an event
Before the six words, the definition makes a structural demand that's easy to skip: professional development is "an integral part of school and local educational agency strategies." Not a purchase. A part of a plan. A workshop bought because the date was open and the speaker was available isn't professional development under the statute, however good the speaker — because it isn't integral to anything. The practical reading: your PD plan should be able to say what each activity is for, in terms of what students need to be able to do.
Part (B): the six words, one at a time
Sustained — "(not stand-alone, 1-day, or short term workshops)." The statute pauses to name what it excludes, which laws rarely do. Sustained means the activity has a duration: it continues after the first session, on purpose. A workshop can be part of sustained PD; it cannot be the whole of it. Rules out: the August keynote as the entire plan. Look for: a defined cycle — what happens in week two, week four, month three.
Intensive — focused enough to change something specific. A season of scattered topics, each touched once, is broad but not intensive. Rules out: the survey course of teaching trends. Look for: one practice goal per cycle, worked on deliberately.
Collaborative — someone else is in it with the teacher: a coach, a colleague, a check-in that asks. Growth alone in a room is exactly the kind that doesn't survive October. Rules out: a resource library and good intentions. Look for: a named person or structure that follows up.
Job-embedded — inside the teaching week, not away from it. Support that requires leaving the building, or waiting for next quarter, isn't embedded in the job. Rules out: the conference as the PD plan. Look for: minutes on the days the teacher actually teaches, tied to what they're trying.
Data-driven — the support responds to what's actually happening in the classroom, and produces a record of how practice is moving. Attendance is data about the workshop, not about teaching. Rules out: a sign-in sheet as evidence. Look for: evidence over cycles — what changed by Day 30, 60, 90.
Classroom-focused — about teaching moves, not policy, compliance, or paperwork. Rules out: the mandatory-training afternoon that counts toward "PD hours." Look for: a goal a teacher can tell every afternoon whether it happened.
What the parenthetical rules out
Read the six words as a checklist and most one-off PD fails four of them at once: it isn't sustained, it isn't job-embedded, it produces no data about practice, and no one collaborates on it after the day ends. The statute doesn't say those workshops are bad. It says they aren't professional development — and Title II, Part A money exists to buy professional development. A keynote can still be the start of something that meets the definition. It can't be the thing itself.
Why a definition in a funding law matters
Title II, Part A funds professional development as ESSA defines it, so the definition is the standard a purchase is judged against — by your Title coordinator, by a state monitor, and by a board member who asks what the money bought. Allowability decisions are local, and the definition isn't the only test (supplement-not-supplant is another). But a PD plan that can point to each of the six words is a plan that survives the audit and October. The funding side is its own article: Title II, Part A: what it can pay for.
Meeting the definition: a planning table
| The statute says | Your plan needs | Evidence you could show |
|---|---|---|
| Integral to strategy | A stated link between the PD and a student outcome | The plan itself, with the "for what" written down |
| Sustained | A cycle with a defined length beyond the first session | A calendar of touches — not one date |
| Intensive | One specific practice focus per cycle | Each teacher's goal, in their own words |
| Collaborative | A person or structure that follows up | Who asks, and how often |
| Job-embedded | Support inside the teaching week | When it happens — on teaching days, in minutes |
| Data-driven | A record of practice moving | Engagement and growth patterns at Day 30, 60, 90 |
| Classroom-focused | Goals stated as teaching moves | "Two student voices before mine, in every discussion" — not "engagement" |
Where the rest of this site picks up
This page is the definition. The others are what it looks like in practice: what PD follow-up is (the definition, lived on a Tuesday), why PD doesn't stick (what happens when the six words are ignored), instructional coaching vs. PD (the collaborative and job-embedded terms in dollars and hours), and Title II, Part A (the money that's supposed to buy it).
Common questions
What is ESSA's definition of professional development?
ESEA §8101(42), as amended by ESSA, defines professional development as activities that are an integral part of school and district strategies for giving educators the knowledge and skills students need, and that are sustained (not stand-alone, one-day, or short-term workshops), intensive, collaborative, job-embedded, data-driven, and classroom-focused.
Is a conference professional development under ESSA?
Not by itself. A conference is stand-alone and short-term, and it happens away from the classroom — it fails the sustained and job-embedded terms on its own. It can be part of professional development if it starts a sustained, job-embedded cycle back at school.
What does "job-embedded" mean in ESSA?
That the professional development happens inside the teacher's actual work — during the teaching week, connected to the classes they teach — rather than away from it. In practice: support on the days a teacher teaches, tied to a specific goal they're working on, in minutes rather than release days.
Does the ESSA definition apply to Title II, Part A purchases?
Yes. The definition sits in ESEA's general definitions section, §8101, and the Department's Title II, Part A guidance cites it directly. Title II, Part A funds professional development as defined there, so the six terms are the standard a PD purchase is judged against. Allowability decisions are still made locally.
PD follow-up is literally our name
PD That Works is a follow-up platform: workshops that set a coachable goal, an AI coach in every teacher's pocket every day after, and Day 30/60/90 reports that land on a leader's desk.
About two minutes. No payment. Nothing goes to teachers until you approve.
