Uganda's Best Schools 2026

Uganda's national examination board, UNEB, releases annual results that independent media outlets compile into detailed school-by-school rankings, covering more than 2,500 schools nationally for the Uganda Advanced Certificate of Education, or UACE. That gives Ugandan families genuinely verifiable, government-sourced data on which schools perform best each year, alongside a small but growing cluster of well-established Kampala international schools offering British and IB pathways.

This ranking is merit-based across both: Uganda's highest-scoring schools by the official 2025 UACE results, alongside the country's most historic traditional schools and Kampala's strongest Cambridge and IB international schools, rather than filtered to one system alone.

How Uganda's School System Works

Ugandan secondary education runs through the Uganda Certificate of Education, taken around Senior Four, followed by the Uganda Advanced Certificate of Education at Senior Six, both administered by UNEB. Uganda's education landscape carries a genuinely distinctive historical layer: several of the country's most prestigious schools, King's College Budo, Gayaza High School, and others, were founded by British missionary societies in the early 1900s and remain among the strongest performers in the national rankings well over a century later. A five-year survey by the Daily Monitor found that Gayaza High School, Immaculate Heart Girls School, King's College Budo, Seeta High School, and Uganda Martyrs Secondary School Namugongo have all appeared among Uganda's top 20 schools in every one of the last five ranking cycles, confirming genuinely sustained excellence rather than single strong years.

Running alongside this national UACE system is Kampala's international school sector, spanning British and IB curricula, serving both the city's expatriate community and Ugandan families seeking an internationally portable qualification. Families weighing that international option against Uganda's own UACE system may find our IB vs Cambridge comparison guide useful background.

1. St. Julian High School Annex, Gayaza

St. Julian High School Annex emerged as the top-performing school in the entire country in the 2025 UACE examinations, posting an average of 17.4 points from 67 candidates, out of a ranking compiled from more than 2,500 schools nationally based on average class performance. Based in Gayaza, Wakiso District, alongside several of Uganda's other most prestigious institutions, its position at the very top of the most recent official national data confirms it as the country's single strongest school by pure UACE results this year. For families researching what actually separates a school performing at this level from a strong national average, our piece on what drives strong exam outcomes covers similar underlying factors around sustained institutional quality.

2. Mt. St. Mary's Namagunga

Mt. St. Mary's Namagunga posted an average of 16.5 points from 126 candidates in the 2025 UACE results, placing it second nationally and confirming its position as one of Uganda's most consistently strong girls' schools. It's one of only nine schools that the Daily Monitor's five-year performance survey identified as appearing among Uganda's top 20 schools in at least four of the last five ranking cycles, a genuinely sustained record of excellence rather than a single strong year.

3. Ntare School, Mbarara

Ntare School posted an average of 16.1 points from 183 candidates in the most recent national rankings, making it the strongest performer from outside the Kampala-Wakiso-Mukono corridor that dominates much of this list. As a public, government-run boys' school based in Mbarara in western Uganda, its top-five national placement confirms that Uganda's strongest academic results aren't confined purely to the capital region.

4. Gayaza High School

Gayaza High School, founded in 1905 by the Church Missionary Society of England, is one of Uganda's oldest and most respected all-girls schools, posting an average of 16.1 points from 164 candidates in the 2025 UACE results. Now enrolling more than 1,570 students, it has appeared among Uganda's top 20 secondary schools in every one of the last five ranking cycles, and its more than 120-year institutional history places it among the most storied names in East African secondary education. Families weighing schools with this kind of century-long track record may find our piece on sustained academic excellence useful context for understanding what genuinely long institutional history contributes to consistent results.

5. St. Mary's Secondary School, Kitende

St. Mary's Kitende is one of Uganda's most recognised private secondary schools, consistently performing strongly across both the O-Level and A-Level national examinations while also building a genuinely distinctive reputation for sports, particularly football, with several Ugandan football stars having passed through its athletics system. That combination of strong academics and athletic dominance gives Kitende a broader national profile than its exam results alone would suggest, appealing to families who want both rigorous coursework and a strong extracurricular sporting culture.

6. King's College, Budo

King's College Budo, officially opened on March 29, 1906, is the only school in Uganda whose alumni include three former heads of state, alongside five former students who went on to reign as kings across three of Uganda's kingdoms. It was the first school in the country to have Ugandans sit the Cambridge School Certificate exam in 1936, and it became Uganda's first mixed-sex institution of higher learning when it admitted girls in 1934. Managed primarily by the Church of Uganda's Namirembe Diocese and set on Naggalabi Hill in Wakiso District, its Old Budonian Club, formed in 1914, remains one of the oldest and most influential alumni networks in the country, giving it an institutional depth matched by very few schools anywhere in East Africa.

7. Uganda Martyrs Secondary School, Namugongo

Uganda Martyrs Secondary School, based in Namugongo, Wakiso District, is another of the small group of schools that has appeared among Uganda's top 20 institutions in every one of the last five UACE ranking cycles, according to the Daily Monitor's sustained-performance survey. Its Catholic affiliation and consistent presence at the top of national rankings place it firmly alongside Gayaza, Budo, and Mt. St. Mary's Namagunga as one of the handful of Ugandan schools with genuinely proven, multi-year academic reliability.

8. Seeta High School

Seeta High School, based in Mukono, appears twice in recent national top-performer data under its main campus and a second listed campus, posting averages in the 15.8 to 15.9 range with candidate numbers among the largest of any school in the rankings. As one of the newer schools identified in the Daily Monitor's five-year survey, alongside more established traditional names like Gayaza and Budo, Seeta's rise confirms that Uganda's strongest performers aren't limited purely to century-old missionary-founded institutions.

9. International School of Uganda (ISU)

ISU delivers the full International Baccalaureate programme from a state-of-the-art Kampala campus, catering to a genuinely diverse international community and preparing students specifically for global university admission. As one of Kampala's clearest IB pathways, it gives internationally mobile families and Ugandan families seeking a globally portable qualification an alternative to the UACE track that dominates the rest of this list. Families weighing this IB pathway seriously may find our curriculum comparison guide useful groundwork.

10. Kampala International School Uganda (KISU)

KISU, based in Kampala's Bukoto neighbourhood, follows the British curriculum through to IGCSE and A-Levels, with a particular emphasis on critical thinking, creativity, and leadership development from the early years through high school. Its British curriculum focus gives Kampala families specifically targeting UK and Commonwealth university admission a well-established alternative to ISU's IB pathway, extending the same kind of British-curriculum continuity we've described among schools in our Kenya schools guide.

What This List Reveals: Century-Old Missionary Schools Still Leading the Rankings

The clearest pattern in Uganda's national exam data is how many of the country's very strongest schools by pure UACE results were founded by British missionary societies more than a century ago and continue to sit at the top of the national rankings today. Gayaza High School, founded in 1905, and King's College Budo, founded in 1906, remain fixtures at the very top of Uganda's academic landscape 120 years later, a genuinely different pattern from the more recently established Nyarugenge and Gasabo District schools that led the equivalent rankings we found researching Rwanda's national exam data.

UACE Track, British Curriculum, or IB: What the Choice Actually Means

For families planning to remain in Uganda long-term, a top UACE school, whether a storied traditional institution like Gayaza or Budo or a newer strong performer like St. Julian High School Annex, remains the most direct route into Uganda's public universities. For internationally mobile families or those planning international university study, ISU's full IB programme or KISU's British IGCSE-and-A-Level pathway offer considerably more global portability. Families still weighing this decision can work through the specifics in our Cambridge IGCSE parent guide.
