Teacher shortage threatens Nigeria’s workforce pipeline

Nigeria’s shortage of nearly 200,000 primary school teachers and overcrowded classrooms across public schools are raising fresh concerns about the country’s ability to build a productive workforce, as education gaps begin to translate into long-term risks for economic growth, labour quality and competitiveness.

With a population estimated at 226 million and roughly 70 percent under the age of 30, Nigeria is one of the world’s youngest countries.

Economists have long argued that this demographic structure offers a potential growth dividend, but only if the education system can equip young people with the skills required in a modern economy.

That link is increasingly under strain.

Data from the Universal Basic Education Commission (UBEC) show that 915,913 teachers currently serve about 31.7 million pupils in primary schools nationwide, translating to a teacher-to-student ratio of 1:35, which is well above the UNESCO benchmark of 1:25.

The deficit in public primary schools alone stands at 194,876 teachers, pointing to a system struggling to keep pace with population growth.

For employers, the consequences are already visible.

“Companies are increasingly hiring for potential but spending more on training because graduates lack foundational skills,” said Peace Chukwuemeka, a human resources expert. “Firms want employees who can think critically and perform from day one, but that gap is widening.”

Experts warn that weak foundational learning, particularly in literacy, numeracy and problem-solving, is gradually feeding into a labour market where formal qualifications do not always translate into productivity.

Jessica Osuere, chief executive officer at RubiesHub Educational Services, said the long-term effect is a workforce that is less competitive in both local and global markets.

“This creates a skills gap where graduates may hold certificates but lack practical competencies needed in modern economies,” she said. “Over time, that weakens productivity, innovation capacity and economic competitiveness.”

Policy ambition meets structural constraints

Nigeria’s education challenge is not new, but its scale is becoming more consequential as the country’s population expands rapidly.

The country has at least 131,377 primary schools serving over 31 million pupils across public and private institutions, according to UBEC data. Yet teacher supply has not kept pace, leaving classrooms overcrowded and educators overstretched.

In some public schools, teachers report managing between 55 and 120 pupils per class, limiting their ability to provide individual attention and assess learning outcomes effectively.

“When classrooms are that crowded, teachers focus on the best-performing students just to keep the system moving,” said Abiola Omosebi, a teacher. “Many others are left behind.”

The result is a widening gap in foundational learning, a critical input for future workforce quality.

A profession losing its appeal

At the centre of the shortage is a profession struggling to attract and retain talent.

Low wages, delayed salary payments and limited career progression have made teaching less attractive compared with sectors such as banking, technology and engineering. Although Nigeria’s minimum wage is officially set at N70,000 per month, many states still pay below this level, particularly in primary education.

“Teachers often work in difficult conditions with little support, and that affects both morale and retention,” Osuere said.

The consequences extend beyond staffing gaps. Poor working conditions are also driving migration of trained educators abroad, further tightening domestic supply.

In rural areas, the challenges are more acute.

“Most teachers posted here try to leave as quickly as possible because basic amenities are lacking,” said Nnenna Elekwachi, a primary school head teacher in Abia State. “We are understaffed, and the workload is heavy.”

Funding gaps and policy trade-offs

Education funding remains a key constraint.

Nigeria’s budgetary allocation to education has ranged between roughly five percent and eight percent in recent years, significantly below UNESCO’s recommended benchmark of 15 to 20 percent. In 2026, the allocation stood at about 6.1 percent, continuing a pattern of underinvestment.

Analysts say the funding gap limits teacher recruitment, training, infrastructure development and learning resources, all of which are necessary to improve outcomes.

Josiah Ajiboye, former registrar at the Teachers Registration Council of Nigeria, noted that Nigeria’s teacher shortage reflects a broader global trend, but with more severe implications locally.

“The global teacher shortage is about 45 million, with Africa accounting for roughly 15 million,” he said. “Nigeria represents a significant portion of that gap.”

Economic stakes rise

For a country seeking to accelerate growth and diversify its economy, the implications are significant.

Weak education outcomes risk undermining Nigeria’s ability to build a skilled workforce capable of supporting sectors such as manufacturing, technology, healthcare and financial services. Employers may face rising costs as they invest more in training, while productivity gains remain constrained.

More broadly, the country risks missing out on its demographic dividend, the economic boost that can come from a large working-age population.

“If foundational education is weak, the demographic advantage can quickly become a liability,” Osuere said

What happens next?

Addressing the teacher gap will require sustained policy focus, including improved funding, better compensation, and stronger recruitment and training systems.

Education experts say restoring the attractiveness of the teaching profession is critical to reversing the trend.

But the window for action is narrowing.

With Nigeria’s population projected to approach 400 million by 2050, the scale of the challenge is set to grow.

Without significant improvements in education quality and teacher availability, analysts warn that the country could struggle to convert its population growth into economic prosperity, leaving its future workforce underprepared for the demands of a rapidly changing global economy.
