Online Teacher Attrition: When It’s Bad, When It’s Good, and What It Costs You

The cost of losing a teacher goes far beyond what you pay for recruiting a replacement once you factor in lost productivity, onboarding time, training, and missed lessons before a new hire performs at full capacity.

When popular teachers leave, students lose familiar faces and established relationships. One resignation can affect:

• Recruitment costs
• Lesson delivery
• Student experience
• Revenue

There is also the quiet cost of negative reviews. They shape how the next candidate sees your company before they ever apply.

Attrition isn't always a resignation, either. A teacher who cuts their hours from 25 a week to eight still counts as “retained” — but your peak-hour capacity has fallen just the same. This capacity attrition can cost as much as losing the teacher outright, without ever showing up in your attrition rate.

Attrition doesn't show up as a line item on an expense sheet. It hides inside a dozen others – higher recruitment costs, more advertising spend, slower sales growth, student complaints. Add it all up and it's rarely small."

— James Thomson, Chief Executive Officer at The Really Great Teacher Company

For an online education business, the commercial sequence of high online teacher attrition is clear:

• More hires are needed simply to maintain teaching capacity.
• Recruitment supports replacement instead of growth.
• Each new teacher must complete onboarding and build lesson volume.
• The business takes longer to recover its hiring investment.
• Real profit falls, even when revenue appears stable.

Pay is a common reason, but it's not the only cause for good teachers to leave. Management capacity, teaching volume, career development and connection can be just as important.

These are some of the most common reasons for high online teacher attrition:

1. Not enough teaching hours. Companies can only offer the hours they have available, and peak time lessons get snatched up quickly. This means they can't offer their teachers enough classes to fill up their schedules.
2. Low pay rates. Where compensation does not align with their skills, expectations or industry standards, high paying platforms or private students are a lot more attractive.
3. Full-time teaching opportunities can offer greater earning potential, consistent hours, benefits, and job security.
4. Limited peer interactions. A remote work environment is less engaging with limited opportunities to build workplace relationships. Without deliberate initiatives, teachers can feel isolated and disconnected from the wider organisation.
5. Unsatisfactory management support. Gallup found that 45% of employees who left voluntarily had not had a proactive conversation about their satisfaction, performance, or future during the three months before leaving.
6. Training ends after onboarding. Teachers stop improving as student expectations, technology and teaching methods change.
7. Strict policies and leave procedures. Rigid operational policies and complex leave processes, especially over holiday periods, can negatively affect employee satisfaction.

Gallup research also found that 42% of employees who left voluntarily believed their manager or organisation could have prevented their departure.

It should be a serious concern when the business is losing skilled, reliable, tenured, teachers it would much rather keep. This is known as regrettable attrition.

It is especially concerning when:

• High-performing teachers are consistently leaving.
• Teachers cite limited hours, weak support, or no development opportunities.
• Your most booked teachers reduce their available hours.
• Departures are concentrated under a particular manager or team.
• New teachers leave soon after onboarding.
• Former teachers share negative experiences publicly.

The latter creates a further compounding problem in making future talent harder to attract.

The effect of isolation is often underestimated. Teachers can be fully booked, well paid, and still leave — because they've never once felt part of something bigger than their own timetable."

— James Thomson, Chief Executive Officer at The Really Great Teacher Company

Zero attrition is neither realistic nor the goal. The aim is not to keep every employee forever — it is to retain the right teachers, understand why others leave, and amicably separate from those who are not a fit.

Some attrition may be healthy when:

• A teacher cannot reliably commit to the lesson volume or schedule required, negatively impacting students ready to learn.
• Their lesson delivery is unreliable - they don't show up to classes, rush through lesson material and activities, or end lessons early.
• They continue to underperform despite fair opportunity, feedback, training and mentorship.
• Their behaviour or values do not align with the organisation and affect the wider team.
• There are integrity concerns, such as policy violations, misrepresented credentials, or student complaints.
• The business has evolved and a teacher's skills no longer match the available work, despite reasonable efforts to retrain or redeploy them.

Losing low-performing teachers is not the same as losing highly rated teachers, and the reason behind each resignation is what turns an attrition number into useful management information. Analyse departures by:

• voluntary and involuntary attrition
• regrettable and non-regrettable attrition
• stated and underlying reason for leaving
• length of service
• average student ratings
• lesson volume and schedule availability

There is no documented education industry number for online teacher attrition specifically. But in our experience, a monthly online teacher attrition rate of anything below 10% is considered low and healthy - though the scale of a business typically indicates what's acceptable to them.

We know of education companies where:

→ delivering 1,000 lessons with a monthly attrition rate of 15-20% was considered high.

→ delivering 100,000 lessons with a monthly attrition rate of 40% was tolerable.

For more specialized teacher roles that typically offer lower hours, such as teaching IELTS prep, maths or science, average monthly attrition can be as high as 30%. Teachers are only booked when there is demand and therefore scheduled classes can be low, while the teacher is expected to keep their availability open.

At The Really Great Teacher Company, our online teacher attrition rate is on average between 5% and 8% per month, with some client accounts as low as 2%.

Due to the diverse nature of our clients and their different schedule requirements across time zones, we are able to provide teachers with fuller schedules by matching them on multiple accounts.

We also offer teachers connection to a global community, ongoing professional and personal development, and 24/7 management support.

Our attrition benchmark isn’t a number we chase. It's what happens by default when the rest of the system — the daily support, training, and community — is actually working."

— Rob Schulenburg, Chief Operations Officer at The Really Great Teacher Company

Once you understand why your good teachers are leaving, you can put measures in place to prevent it.

Multiple scheduling options → If teachers don’t have enough classes booked to make a living, they will leave no matter what. Offering multiple class types, time zones, students, and ultimately more hours greatly improves retention.

Lesson availability → As early as the advertising stage, ensure the schedule type is clearly communicated. Whether you offer guaranteed hours, a flexi schedule where teachers can offer availability within certain peak times and a set number of classes per week, or appointment based classes, so applicants can manage their expectations upfront.

Pay rate transparency → Be crystal clear about the lesson rate and currency per hour, so teachers can calculate an expected income based on the average number of lessons they would teach.

Community and connection → When teachers are isolated, it affects their lessons. Real opportunities to connect go a long way toward motivation.

Training infrastructure → Keeping teachers current on new methodologies, tools, platforms and product types keeps them inspired and improves lesson quality.

Management support → Building relationships with individuals helps prevent issues before they arise, and keeps teachers motivated and thriving.

Online teacher retention isn't particularly complicated on paper. What's hard is doing it consistently, for every single teacher, day in and day out, at scale. That's the part most internal teams don't have the bandwidth for, but is so important to get right.”

— James Thomson, Chief Executive Officer at The Really Great Teacher Company

Retention begins with who you recruit and how well the role matches their skills, values, personality and expectations.

This is why our Teacher Management and Development as a Service (TMaaS) covers the full teacher lifecycle. We recruit and screen online teachers - assessing potential, value alignment, personality and emotional intelligence over and above the standard requirements. We onboard, manage, develop and support them.

Because we recruit and manage teachers across multiple markets and time zones, we can often give a teacher more hours than a single platform could offer alone — one of the most practical ways to prevent both resignation and the quiet, harder-to-see attrition of reduced hours.

TMaaS eliminates your online teacher recruitment and replacement costs. All our clients pay, is a set rate for every lesson taught.

The purpose is not simply to make teacher replacement easier. It's to manage teachers well enough that it becomes less common, and teacher recruitment actually supports business growth and not just filling attrition.

If you battle with high online teacher attrition and don't have the internal capacity or resources to effectively keep it under control, we can help.

How do I calculate my teacher attrition rate?
Divide the number of teachers who left in a period by your average teacher headcount in that same period, then multiply by 100.

Is high teacher attrition always a bad thing?
No, not necessarily. Losing under-performers who are not improving, or teachers who are not a culture fit, can actually be healthy for the business. High attrition is only a problem when good teachers consistently leave.

How can I reduce online teacher attrition?
Start by identifying why teachers are actually leaving, since the fix depends on the cause. The most common ways are offering more hours, scheduling flexibility, being transparent about pay, building a path into leadership, and giving teachers regular, proactive support.
