What an instructional coach actually costs.

By Yechiel · Founder, PD That Works. Yechiel builds PD That Works — the workshops, the daily AI coach, and the Day 30/60/90 reports — and wrote every page on this site.

A great coach can hold a few dozen relationships. You have a whole faculty. That sentence is the whole argument for what follows, but a board doesn't approve arguments — it approves numbers. So here are the numbers: what a coach is paid, what a coach costs once benefits are counted, how many teachers one coach can actually reach, and what that works out to per teacher. Then the honest contrast with the daily follow-up layer, which is a different instrument at a different price.

The salary, from the only federal source

The federal government doesn't track "instructional coach" as a job title. The closest category is instructional coordinators, and the Bureau of Labor Statistics puts the numbers this way for May 2024: a median of $74,720, with the lowest 10 percent earning under $46,560 and the highest 10 percent over $115,410 — about 232,600 people in the role nationally (BLS Occupational Outlook Handbook). Your district's number will sit somewhere on that range depending on region, contract, and whether the coach is on the teacher salary schedule with a stipend or in a separate line.

Use the median for the arithmetic below and swap in your own figure; the shape of the result doesn't change.

What a coach costs the district

Salary isn't cost. For state and local government employees, benefits — health, retirement, paid leave — run 38.4 percent of total compensation, with wages the other 61.6 percent (BLS Employer Costs for Employee Compensation, March 2025). Applied to the median:

SalaryFully loaded (÷ 0.616)
Lowest decile$46,560about $75,600
Median$74,720about $121,000
Highest decile$115,410about $187,000

So a median coach is roughly a $121,000-a-year decision, before office space, travel, or the substitute coverage that release time requires.

The ratio: how many teachers can one coach reach

A real coaching touch is a classroom observation and a debrief — call it 45 minutes in the room and 30 in conversation, 75 minutes per teacher. Here's what that costs in hours across a week:

CaseloadWeekly touchBiweekly touch
60 teachers75 hours — doesn't fit in a week37½ hours — the whole week, no prep, no meetings
40 teachers50 hours25 hours
30 teachers37½ hours — the whole week19 hours
20 teachers25 hours — workable, with room to do the job well12½ hours

The number that actually works for weekly coaching is a caseload of about twenty. Biweekly stretches to forty at the cost of half the frequency. Either way, on a sixty-teacher faculty with one coach, most teachers are not on the caseload. That's the arithmetic that rations coaching to the newest or the struggling — the coaching works; it just reaches a few.

Cost per coached teacher

Divide the loaded cost by the caseload:

CaseloadSalary only (median)Fully loaded (median)
15 teachersabout $5,000 per teacherabout $8,100 per teacher
20 teachersabout $3,700 per teacherabout $6,000 per teacher
30 teachers (biweekly-ish)about $2,500 per teacherabout $4,000 per teacher

That's not a criticism of coaches — it's the honest price of judgment delivered in person, and worth every dollar for the teachers who get it. It is also why the question "should we hire a coach?" is really two questions: for whom, and what does everyone else get.

The forty who aren't on the caseload

To coach a sixty-teacher faculty weekly at a twenty-teacher caseload, you need three coaches — about $364,000 a year fully loaded at the median. Almost no school does that. Most hire one, which means a coaching program that costs $121,000 and, by the hours, reaches a third of the faculty. The remaining forty get the workshop and nothing else — the exact condition under which PD doesn't stick.

The honest per-teacher number for a faculty, then, isn't $6,000. It's $121,000 spread across sixty teachers, two-thirds of whom get no coaching: roughly $2,000 each on paper and, for forty of them, nothing in practice.

When the number is worth paying

It often is. Anything that requires seeing the room — observation, modeling, co-teaching — belongs to a person. So does the hard conversation, a new teacher's first year, and a teacher in a hard season. The research is on the side of coaching: a meta-analysis of 60 causal studies found it among the most effective PD forms ever measured, with more hours not producing better outcomes — specificity beats dosage. The full comparison of workshops, human coaching, and daily follow-up is on its own page: instructional coaching vs. professional development.

The point of the arithmetic isn't to talk a school out of a coach. It's to name what one coach can and can't reach, so the rest of the faculty isn't left with the keynote.

The contrast, stated honestly

PD That Works' pricing is published: the Quarterly Cycle is $1,500 for 90 days and one cohort of up to 30 teachers; annual tiers run School Starter at $4,500 for 30 teachers, Growth at $9,000 for 60, Pro at $14,500 for 100, and Plus at $22,000 for 150. Across the annual tiers that's $150 per teacher per year — for every teacher, every teaching day.

It isn't the same instrument. The AI doesn't observe, doesn't model, doesn't sit with a teacher after a bad period. What it does is the part no coach has hours for: showing up on Tuesday, for all sixty, and remembering. A school with one coach and daily follow-up gets judgment for twenty and persistence for sixty. We make coaches better, we don't replace them.

Common questions

How much does an instructional coach make?

The federal government tracks the role as "instructional coordinators": a median of $74,720 in May 2024, with the lowest 10 percent under $46,560 and the highest 10 percent over $115,410, according to the Bureau of Labor Statistics. Fully loaded with benefits at the state-and-local-government average of 38.4 percent of compensation, the median coach costs a district about $121,000 a year.

How many teachers should an instructional coach have?

Work it in hours. A 75-minute weekly touch — observation plus debrief — for sixty teachers is 75 hours a week; for twenty it's 25 hours, which leaves room to do the job well. A caseload of about twenty is workable for weekly coaching; biweekly stretches to about forty at half the frequency.

What does an instructional coach cost per teacher?

At the federal median and a twenty-teacher caseload, about $3,700 per coached teacher in salary alone and about $6,000 fully loaded. Spread across a sixty-teacher faculty with one coach, it's roughly $2,000 per teacher on paper — and nothing in practice for the forty who aren't on the caseload.

Is an instructional coach worth the cost?

For the teachers a coach can actually reach, usually yes: a meta-analysis of 60 causal studies found coaching among the most effective forms of PD ever measured. The problem is reach, not effect. The honest question is what the rest of the faculty gets, and the answer shouldn't be "the workshop and nothing else."
