The world is grappling with a significant teacher shortage crisis. According to UNESCO, an additional 44 million teachers are needed by 2030 to achieve universal primary and secondary education (UNESCO, 2024). This shortage is not just a statistic; it has profound implications for the quality of education and the future of societies worldwide.

A simple glance through teacher forums, such the incredibly popular International Schools Review, reveals a dark abyss that’s peppered with bleak testimonials:

“I believe that many of my colleagues feel unheard and mistreated – this has been shown time and again in our staff surveys. Of course, someone in the inner sanctum would not be subject to the toxic, exclusionary, bullying behaviour meted out by SLT; it does not mean it does not exist. Some colleagues are leaving this academic year due to feeling disenfranchised.“

“The school is working to improve vertical curriculum alignment, but since the school has been in operation for many years, it is surprising that the curriculum is such a mess, at least in the department I taught in. I think that will get better in the next few years though. If you order your materials the year before, you can get things, but don’t expect to have them at the beginning of the school year. If you need classroom supplies like pencils, markers, erasers, etc, good luck.”

– A teacher at a school in Brazil, May 2025

“Walking through the corridors is akin to walking through a zoo. Children scream, shout and run about with no regard for safety. No teacher dares make an attempt to challenge this behaviour for various reasons. Two of which are fear of the parents and lack of support from the principal.”

These reviews, and others like them, offer some insight into the world of teaching at an international level, and go some way to explaining why so many teachers are quitting the profession. In today’s blog post, I aim to describe the key factors that are driving this exodus, and describe some much needed advice for all stakeholders who want to retain their brightest and best teachers for years to come.

Understanding the Crisis

Several factors are contributing to the current global teacher shortage:

  • High Attrition Rates: Many teachers are leaving the profession due to burnout, low salaries, and lack of support. In the United States, for example, 51,000 teachers quit their jobs in 2023 alone (Devlin Peck, 2025).
  • Uneven Distribution: Rural and underserved areas often struggle more with teacher shortages, exacerbating educational inequalities (UNESCO, 2024).
  • Aging Workforce: A significant portion of the teaching workforce is nearing retirement, and there aren’t enough new teachers to replace them (Devlin Peck, 2025).

Impacts on Education

When there aren’t enough teachers in schools, this leads to:

  • Larger Class Sizes: Overcrowded classrooms make it challenging to provide individual attention to students (UNESCO, 2024).
  • Reduced Educational Quality: Unqualified or overburdened teachers may not deliver the curriculum effectively, impacting student learning outcomes (Education Week, 2025).
  • Increased Inequality: Disadvantaged communities suffer the most, widening the education gap between different socioeconomic groups (UNESCO, 2024).

Strategies for Addressing the Shortage

To mitigate the teacher shortage crisis, stakeholders can consider the following approaches:

#1: Enhancing Teacher Training and Support

  • Mentorship Programs: Implementing structured mentorship can help new teachers acclimate and reduce early-career attrition (Frontline Education, 2025).
  • Professional Development: Ongoing training opportunities keep teachers engaged and improve teaching quality (Education Week, 2025). One of my favourite platforms for this is the excellent Great Teaching Toolkit. My Blog Index for Teachers is also a very popular for those seeking free, yet high-quality, CPD material.

#2: Improving Compensation and Working Conditions

  • Competitive Salaries: Offering salaries that reflect the importance of the teaching profession can attract and retain talent (Devlin Peck, 2025). If pull factors, such as decent pay, are not present to begin with then many fresh graduates are simply not going to choose teaching as a profession.
  • Work-Life Balance: Flexible working arrangements and manageable workloads can reduce burnout (The Guardian, 2024).

With respect to managing workloads we must not forget about teachers who work online, too. Jessica Robinson from The Speaking Polymath write this great post for me back in 2022 with some good tips for preventing burnout whilst teaching online.

#3: Alternative Pathways into Teaching

  • Career Changers: Encouraging professionals from other fields to transition into teaching can bring diverse experiences into the classroom (Education Week, 2025).
  • Residency Programs: Programs like Urban Teacher Residencies provide hands-on training and have shown success in retaining teachers in high-need areas (Wikipedia, 2023).

#4: Policy Interventions

  • Legislative Support: Policies that provide financial incentives, such as student loan forgiveness or housing assistance, can make teaching more attractive (UNESCO, 2024).
  • Streamlining Certification: Simplifying the certification process without compromising quality can help fill vacancies more quickly (New York Post, 2025).

What does the future hold?

In addition to the above points, there’s a massive issue looming in the background that virtually no one is talking about: People simply aren’t having as many babies as they used to. Fertility rates have been falling steadily across much of the developed world for decades, and many countries are now well below the replacement rate of 2.1 children per woman. For example, South Korea’s fertility rate hit a record low of 0.72 in 2023, while countries like Japan (1.26), Italy (1.22), and China (1.09) are also experiencing unprecedented demographic decline (World Bank, 2024; United Nations, 2023).

This trend has profound implications for the future of education. While teacher shortages are currently critical, the long-term demand for teachers is likely to decline as school-age populations shrink. According to projections by the UN Department of Economic and Social Affairs, the number of children aged 5–14 will decline significantly in many high-income countries by 2050. This suggests that some of today’s recruitment pressures may ease over time: not due to systemic reform, but because of demographic inevitability (UN DESA, 2022).

In essence, what this means is that current teacher shortages are likely to persist for a good while yet but by around 2050 we may see an inversion of this scenario as far fewer children exist to begin with. With the advent of generative AI, and it’s subsequent widespread adoption, we may soon see the role of educator becoming fully automated as schools cut back on salaries due to low student numbers.

Conclusion

The teacher shortage is a multifaceted issue requiring coordinated efforts from governments, educational institutions, and communities. By investing in teacher support, improving working conditions, and implementing innovative recruitment strategies, we can work towards a future where every child has access to quality education delivered by qualified and motivated teachers.

In terms of the longer term plan for teachers (i.e. 20 – 40 years down the road), I advise everyone to keep busy with studies and acquire as many skills as you can – we may soon be replaced by automated systems, and the ability to seamlessly transfer to another profession, or to capitalise on your skills in a business capacity, will be a tremendous advantage (hence my development of Corporate Training programs, which are becoming incredibly popular).
