Secondary education: the neglected link in human capital

West Africa managed to get its children into primary school, then left them standing at the foot of the next step. The gross enrolment ratio in secondary education in Sub-Saharan Africa stalls at 45.9%, barely more than half the global average (77.3%): in other words, one African adolescent in two remains out of secondary school. This is not a statistical footnote, it is the breaking point of the region's human capital. Where primary schooling has become the norm, access to lower- and upper-secondary school remains a privilege, and the gap with the rest of the world is not closing, it is widening. The question, then, is not whether the region can educate its youth, but whether it decides to build the missing staircase between primary schooling attained and secondary schooling denied.

One region, trajectories that the average flattens out

Behind the regional figure lies a dizzying spread. World Bank data place Ghana at the top, with a secondary gross enrolment ratio of 75.7%, followed by Côte d'Ivoire (65.3%) and Togo (63.4%). At the other extreme, Niger brings up the rear at 19.9%, a ratio of nearly 1 to 4 with Ghana. Benin, at 43.6%, sits below the Sub-Saharan average and shares the region's structural vulnerability. This ranking does not track the map of wealth or of climate: neighbouring countries with comparable conditions appear at both ends. The hierarchy of secondary enrolment tells less a story of inevitability than a story of public policies upheld or abandoned. That is good news, because policies, unlike geography, are a matter of choice.

The broken step: primary advances, lower-secondary falls away

The real breaking point is not entry into school, but the passage from primary to lower-secondary. The region has built a respectable primary floor without constructing the secondary staircase that was meant to extend it. In Benin, 61.6% of an age cohort complete primary school, but only 27.9% finish the first cycle of secondary: more than half of the students who finish primary school vanish before the end of lower-secondary. The step between the two levels collapses, and it is there, precisely, that the losses occur. Comparing primary and lower-secondary completion country by country means measuring the height of this broken step, and therefore the exact scale of the task.

In Benin, six children in ten complete primary school, but fewer than three in ten finish lower-secondary. School does not lose its students at the door, it loses them on the broken step toward secondary education.

Ghana retains, Benin drops out: the demonstration through facts

Comparing two neighbouring systems is the best antidote to fatalism. Ghana retains 85.1% of its students to the end of lower-secondary and enrols 75.7% of its age cohort in secondary education; Benin stalls at 27.9% first-cycle completion and Niger at 11.9%. The completion gap between Ghana and Benin (85.1% versus 27.9%) exceeds 57 percentage points: this is not a nuance, it is a chasm. It provides the clearest possible proof that a system can retain its students all the way through lower-secondary when it makes them a budgetary and political priority. The signal is clear: what sets the two trajectories apart is not wealth or climate, but the intensity and consistency of the public effort devoted to secondary education.

Reduced to simple orders of magnitude, lower-secondary completion draws three groups of countries facing the same educational promise very unequally.

• The systems that retain. Ghana (85.1%) and Côte d'Ivoire (70.8%) graduate the clear majority of an age cohort from lower-secondary, proof that near-universal secondary education is attainable in West Africa.
• The stalled pack. Togo (56.6%) aside, Senegal (38.7%), Mali (28.1%), Benin (27.9%) and Burkina Faso (27.9%) are stagnating: barely one child in three finishes lower-secondary there, despite a primary cycle often well underway.
• Extreme drop-out. Niger graduates only 11.9% of its age cohort from lower-secondary, one child in eight: secondary schooling there remains a minority privilege, reserved for a sliver of the youth.

Three decades to understand: a choice, not a natural slope

A single year's snapshot does not tell whether a country is rising or stalling. The long series, by contrast, settles the matter. Between 2000 and 2024, Ghana more than doubled its secondary gross enrolment ratio, from 32.6% to 75.7%, a continuous and cumulative climb. Senegal tripled its own, from 15.2% to 44.1%. Niger, starting from 6.3%, painfully reaches 19.9% a quarter of a century later: it is progressing, but so slowly that the absolute gap never closes. Benin, for its part, illustrates the most disappointing trajectory: after peaking at 55.1% in 2015, its ratio fell back to 43.6% in 2022. This regression is no accident; it is a reminder that an educational gain left untended is lost, and that a decade of divergent policies is enough to durably separate countries that started from the same point.

Where the losses occur: two hinges, two locks

The haemorrhage of secondary education is no mystery: it concentrates at two identifiable hinges. The first is the transition from primary to lower-secondary. In Niger, only 58.3% of primary leavers make it there, which means that nearly four children in ten who finish primary school never cross the threshold of lower-secondary, against more than nine in ten in Ghana and Côte d'Ivoire. The second hinge is the passage from lower- to upper-secondary, where the losses accelerate still further: upper-secondary completion collapses to 8.4% in Benin and 1.6% in Niger. The summit of the educational pyramid, upper-secondary, remains out of reach for more than seven Sub-Saharan youths in ten, with upper-secondary completion capping at 28% for the region as a whole.

These two locks close for concrete and documented reasons. The shortage of nearby lower-secondary schools in rural areas stretches distances until they become prohibitive. The opportunity cost of adolescent labour weighs on modest families, who give up on prolonged schooling as soon as a child can contribute to the household income. Early marriages remove girls from the system before the end of the cycle. And, in the Sahel, insecurity adds a factor of brutal collapse: according to UNICEF, more than 11,000 schools have been closed in the region because of conflict, depriving entire cohorts of even theoretical access to school. These mechanisms are not a matter of cultural inevitability; they are material obstacles, and therefore ones that targeted policies can loosen.

The cumulative result of these locks can be read in the share of adolescents quite simply out of school. In Niger, non-enrolment affects 64.9% of adolescents of lower-secondary age, nearly two in three, and 52.8% in Mali; at the other end of the spectrum, Ghana contains it at 10.6%, barely one in ten. Benin, at 34.4%, sits between these extremes, but still leaves a third of its lower-secondary-age youth outside any establishment. The 54-point gap between Niger and Ghana does not measure a difference in wealth: it measures the distance between a system that has made secondary education a priority and another where it remains reserved for a minority.

The cost of inaction: 53 million young people left by the wayside

Weak secondary education is not paid for only in empty classrooms; it is paid for on the labour market and across the entire economy. In 2023, 53 million young people in Sub-Saharan Africa were not in employment, education or training, a regional rate of 20.4%. This is the direct social translation of a system that does not carry its adolescents to the end of their education: without completed lower- or upper-secondary schooling, a massive share of the youth reaches adulthood with no qualification, no safety net and no horizon. This lost cohort is not a passing cost, it is human capital durably amputated, at the very moment when the region begins the demographic transition that should, in theory, carry it forward.

The problem is aggravated by the near-total absence of the bridge that was meant to connect school to the world of work. Technical and vocational education, meant to offer a qualifying way out to those who do not continue on the general track, accounts for only 1.8% of secondary enrolment in Sub-Saharan Africa. In other words, the region has neither retained its adolescents in general education, nor built the vocational alternative that could have qualified them another way. The broken step of secondary education thus leads, for want of a lateral ramp, to youth unemployment and inactivity, turning an educational deficit into an economic one.

In 2023, 53 million Sub-Saharan youths were out of employment, education and training. Neglected secondary education is not a school problem: it is an economic bill paid every year.

What national averages hide: the territorial divide

A national figure is only an average, and averages conceal the essential. Behind Benin's rate of adolescents out of school lies a brutal territorial divide: 48.3% of rural adolescents are out of the system, against 31.2% in cities. In Niger, the gap is more staggering still, 80.8% in rural areas against 41.3% in urban areas. Place of birth therefore decides, more surely than talent, access to lower-secondary school. This divide, which no aggregate statistic reveals, calls for a geographically targeted response: build lower-secondary schools where adolescents drop out, and not uniformly according to averages that correspond to no local reality.

Wealth opens an even more brutal gap than territory. For lower-secondary completion, the parity index between the poorest and the richest quintile falls to 0.15 in Sub-Saharan Africa: in concrete terms, a child in the bottom decile has a derisory chance of finishing lower-secondary compared with a wealthy child. Secondary education, across much of the region, remains a good reserved for those who can bear both its direct cost and its opportunity cost. Added together, the rural divide and the wealth divide draw the true face of neglected secondary education: that of a rural and poor youth excluded from a cycle that national statistics falsely present as accessible to all.

Gender: a gap that reverses across borders

Gender inequality in secondary education does not follow a single pattern, and that is precisely what makes steering it complex. In some countries, girls have now overtaken boys: in Senegal, their secondary gross enrolment ratio reaches 50.2% against 38.3% for boys, and in Burkina Faso 33.2% against 26.8%. Elsewhere, the traditional hierarchy persists: in Benin, girls remain clearly behind, at 40.3% against 46.7% for boys, as in Togo and Mali. This reversal across borders forbids any uniform regional diagnosis. A gender policy effective in Senegal, where the challenge is now to keep boys from dropping out, would be counterproductive in Benin, where it is girls' schooling that must be supported as a priority. Without data disaggregated by sex and by country, public action aims blind.

A sacrificed age cohort: the global scale of drop-out

The West African phenomenon is part of a crisis of global scope. In 2023, 64 million adolescents of lower-secondary age were out of school worldwide, 15% of that age cohort, and Sub-Saharan Africa alone accounts for 39% of the total out-of-school population. The region is therefore not merely behind: it carries a disproportionate share of the planet's out-of-school burden. A caution is nonetheless in order regarding these figures, because global out-of-school estimates have been sharply revised upward by UNESCO's new models: the real scale of the phenomenon was underestimated in earlier series. The undersizing of the problem in past statistics is itself revealing of the measurement deficit that hampers action.

The CRAD angle: measure the broken step before trying to repair it

Steering secondary education suffers from an often invisible ailment: the lack of fine-grained, recent and localised data. The available completion and transition series frequently date from 2015 to 2018, and disaggregation by setting (rural or urban) and by wealth level rests on household surveys spaced out over time. The result is an attempt to steer an education policy with a dashboard half of whose dials are out of date. Yet the hinges where the losses occur, the primary-to-lower-secondary transition and the lower-to-upper-secondary passage, require precisely the kind of fine and repeated measurement that national averages do not provide.

This is the conviction that guides CRAD's work on human capital: an education statistic has value only if it is geolocated, disaggregated by sex and by setting, and repeated from one year to the next. CRAD equips ministries and donors with monitoring-and-evaluation systems and up-to-date sectoral databases, capable of targeting the areas and cohorts that drop out rather than reasoning in misleading averages. Measuring the broken step between primary and lower-secondary, area by area and group by group, is the prerequisite for any credible policy of school retention. Without this compass, educational investment moves forward blind, and distributes resources where they close none of the real locks on drop-out.

Fundamentally, West African secondary education is not an insoluble pedagogical challenge: the countries that are making progress, Ghana foremost, show that the recipe is known and transferable. It is a problem of political consistency and of steering by data. The systems that retain their students are those that set themselves a completion target, sustain the effort over a decade, and measure their results where they are decided, at the hinge of each cycle. Those that lose their students do not lack human potential: they lack an instrument to see where, exactly, the staircase broke. Repairing the neglected link in human capital means first deciding to measure it, then never letting go of it.
