Choosing your child's school can affect their academic and personal growth. A good secondary school should provide a supportive learning environment, experienced teachers and opportunities to explore different interests. Here, we'll look at the best secondary schools in Dublin and what to consider before deciding. We've included fee-paying and non-fee-paying schools in one ranking, with advice on comparing schools and applying for a place.
Key Takeaways
- Coláiste Íosagáin leads our Dublin Top 20, followed by Coláiste Eoin and Muckross Park College.
- The ranking includes fee-paying and non-fee-paying schools, as well as girls', boys' and mixed settings.
- Academic performance and third-level progression figures don't measure every aspect of a school's quality.
- Parents should compare subject choices, school ethos, commuting distance and student support before making a shortlist.
- Admissions deadlines and selection criteria vary, so check each school's published policy.
Coláiste Íosagáin takes first place in our Dublin Top 20, followed by Coláiste Eoin and Muckross Park College. This is an editorial ranking, not an official government league table. Families should also consider each school's ethos, subject choices, admissions criteria and suitability for the individual student.
How Are the Best Secondary Schools in Dublin Ranked?
Our Dublin Top 20 is an editorial selection, not an official school league table. When comparing the best secondary schools in Ireland, academic performance and third-level progression provide useful context alongside school type, curriculum and the student experience. However, don't treat the precise positions as independently verified measures of educational quality, and a highly ranked school won't necessarily suit every student.
School rankings offer a useful starting point, but they cannot capture every aspect of the student experience. Leaving Certificate results and third-level progression figures provide some context, although neither measures the overall quality of teaching or student support. The Department of Education's Inspectorate publishes reports covering areas such as teaching, learning and school leadership, which families can consult alongside these rankings.³
Leaving Certificate results and third-level progression figures are useful indicators, but they don't tell the whole story. Student numbers can also help families understand an institution's size and the environment their child might experience. The Department of Education publishes annual post-primary enrolment figures, allowing families to compare school populations without treating size as a measure of quality.¹⁰
students were enrolled in post-primary education in September 2024, according to the Department of Education.⁹
A former pupil's excellent Leaving Certificate results don't guarantee that another student will achieve the same grades. Students have different strengths, interests and learning needs, and the environment that suits one person may not suit another. Use the ranking to identify potential schools, then compare them against your own priorities.
- Academic results and third-level progression provide context, not a definitive league table.
- Inspection reports offer further insight into teaching and school leadership.
- A higher ranking doesn't guarantee a better fit for every student.
The Top 20 Secondary Schools in Dublin
Dublin offers a wide range of secondary schools for students from different backgrounds. This ranking includes fee-paying and non-fee-paying schools, each with its own approach to education and student development. Families comparing options across Ireland can also consider the top-ranked schools in Cork, although location and admissions will influence which schools are practical choices. Let's take a look at the top-ranked secondary schools in Dublin.
The 10 Best Secondary Schools in Dublin
Some of the top secondary schools in Dublin include Coláiste Eoin, Coláiste Íosagáin and St Michael's College. These institutions differ in their school ethos, fee status and the programmes they offer. The table below brings the top ten together so families can compare their options.
| Dublin rank | School | Location | Intake | Fee status |
|---|---|---|---|---|
| 1 | Coláiste Íosagáin | Booterstown | Girls | Non-fee-paying |
| 2 | Coláiste Eoin | Booterstown | Boys | Non-fee-paying |
| 3 | Muckross Park College | Donnybrook | Girls | Non-fee-paying |
| 4 | Catholic University School | Leeson Street, Dublin 2 | Boys | Fee-paying |
| 5 | Santa Sabina Dominican College | Sutton | Girls | Non-fee-paying |
| 6 | St Colmcille's Community School | Knocklyon | Mixed | Non-fee-paying |
| 7 | Mount Anville Secondary School | Dublin 14 | Girls | Fee-paying |
| 8 | Gonzaga College | Ranelagh | Boys | Fee-paying |
| 9 | St Michael's College | Ballsbridge | Boys | Fee-paying |
| 10 | Loreto College, St Stephen's Green | Dublin 2 | Girls | Fee-paying |
Coláiste Íosagáin and Coláiste Eoin stand out at the top of our list. They're both in Booterstown, but the former's a girls' school and the latter a boys' school. Families should know that the language of instruction matters, as studying subjects through Irish is different from taking Irish as a separate subject.²
The third-place Muckross Park College is another non-fee-paying option for girls in Donnybrook. Santa Sabina Dominican College in Sutton and St Colmcille's Community School in Knocklyon complete the non-fee-paying schools in the first ten. St Colmcille's is the only mixed school in this section of the ranking.
Catholic University School at number four is the first fee-paying option, with Gonzaga College and St Michael's College appearing further down the top ten. Mount Anville Secondary School and Loreto College, St Stephen's Green, are both girls' schools. Although all five charge tuition fees, their subject choices, extracurricular activities and school environments can differ considerably. Compare these features individually rather than assuming that fee-paying schools offer the same experience.
Secondary Schools Ranked 11–20
The schools ranked 11–20 broaden the selection beyond the very top. Each has its own subject offering, admissions arrangements and learning environment. Reviewing these differences can be more useful than focusing on small gaps in ranking positions.
| Dublin rank | School | Location | Intake | Fee status |
|---|---|---|---|---|
| 11 | The Teresian School | Donnybrook | Girls | Fee-paying |
| 12 | Castleknock College | Castleknock | Boys | Fee-paying |
| 13 | Belvedere College S.J. | Dublin 1 | Boys | Fee-paying |
| 14 | Mount Sackville Secondary School | Chapelizod | Girls | Fee-paying |
| 15 | Alexandra College | Milltown | Girls | Fee-paying |
| 16 | St Andrew's College | Booterstown | Mixed | Fee-paying |
| 17 | Holy Child Killiney | Killiney | Girls | Fee-paying |
| 18 | Loreto Abbey Dalkey | Dalkey | Girls | Fee-paying |
| 19 | The High School | Rathgar | Mixed | Fee-paying |
| 20 | St Conleth's College | Ballsbridge | Mixed | Fee-paying |
The schools ranked 11–20 cover a wider geographical area, from Donnybrook and Castleknock to Dalkey and Rathgar. The Teresian School, Castleknock College and Belvedere College occupy the first three positions outside the top ten. Mount Sackville Secondary School in Chapelizod and Alexandra College in Milltown follow them, giving families several more locations to consider.
St Andrew's College in Booterstown, The High School in Rathgar and St Conleth's College in Ballsbridge are mixed schools. Holy Child Killiney and Loreto Abbey Dalkey are girls' schools. Families interested in comparing more options can use the Schooldays.ie directory to find secondary schools throughout County Dublin.⁶
All ten schools in this part of the ranking charge tuition fees. That makes the total cost of attendance an important consideration alongside location, subject choices and school ethos. Families considering a move outside Dublin may also want to compare secondary schools in Limerick, where a different range of local options is available. Rather than focusing on small ranking differences, compare schools based on what your child actually needs.
- Coláiste Íosagáin, Coláiste Eoin and Muckross Park College occupy the top three places.
- The top ten includes Irish-medium, fee-paying, non-fee-paying and single-sex schools, plus one mixed school.
- All schools ranked 11–20 are fee-paying, with different locations and student intakes.
Fee-Paying vs Non-Fee-Paying Secondary Schools in Dublin
Because secondary education is largely publicly funded in Ireland, non-fee-paying schools make up a substantial part of the system. Dublin also has a wide selection of fee-paying secondary schools, including several in this ranking. However, higher fees don't necessarily mean a school is a better fit for an individual student.
Extracurricular activities can make a considerable difference to a student's experience, particularly if they have a strong interest in sport, music or drama. Some Dublin schools offer extensive sporting programmes, while others may appeal to students with different interests. Compare the facilities, teams and activities at individual schools rather than assuming that fee-paying institutions always offer more.
Non-Fee-Paying Secondary Schools
Non-fee-paying schools do not charge tuition fees, although families may still face costs for uniforms, books, transport and extracurricular activities. These schools offer a range of subjects, facilities and support services, which vary between institutions. Parents should compare the curriculum, school ethos and admissions criteria before applying.⁵
Fee-Paying Secondary Schools
Fee-paying secondary schools charge tuition fees, and the Department of Education publishes separate enrolment figures for these institutions.⁴ Additional costs may apply for activities, transport and other services, so families should check what's included. Fees alone don't determine teaching quality or whether a school's curriculum and support will suit a particular student.
What Do School Fees Actually Cover?
The published tuition figure might not reflect everything a family will spend during the school year. Ask whether meals, transport, technology, music lessons and school trips are included or charged separately. If the school offers Transition Year, request a breakdown of its programme costs rather than assuming they're covered by the standard tuition fees.
Before committing, request the current fee schedule in writing and confirm the payment deadlines. Find out whether tuition increases between year groups, whether instalment plans or financial assistance are available, and what the refund policy says about deposits. This will help you compare the total costs of different schools before accepting an offer. The same approach works well when comparing secondary schools in Waterford or elsewhere in Ireland, especially if your family is planning to relocate.
- Non-fee-paying schools can still involve costs for uniforms, transport and activities.
- Fee-paying schools may charge extra for trips, programmes and other services.
- Compare total costs, facilities and subject choices rather than fees alone.
How to Choose the Right Secondary School in Dublin
When selecting the right school for you or your child, consider several factors to ensure a good match. Consider your needs, interests, and goals to find a school that meets your requirements. Academic achievements, facilities, teaching approaches, and the overall school environment are all worth considering before you decide.
Academic Performance, Subjects and Programmes
Start by looking at each school's track record in state examinations. Also check which subjects and programmes are available, especially if you have a specific Leaving Certificate pathway in mind. Academic results matter, but subject choice and the support available to students can be just as important.
There is certainly no getting around the mountain of work that comes with a Leaving Certificate education across all subjects. If you want to do well, you will need to keep your head down and study smart as well as hard. A school that offers suitable subjects, effective teaching and a supportive learning environment can help students manage these demands.
Subject choice matters long before Leaving Cert, particularly when pupils move from primary school into the Junior Cycle. The National Council for Curriculum and Assessment provides guidance to help families understand this transition and the subjects available.⁸ It's also worth discussing what students might want to do after school rather than treating university as the only successful outcome. The Higher Education Authority examines different pathways involving post-primary education, further education and apprenticeships.⁷
School Location, Ethos and Student Support
Ask yourself questions and find out what matters to you as a student. If you are an athlete, you will want to investigate the sporting facilities on offer at the school and the track record of the teams in your sport. Consider the activities offered by the school, its facilities, teaching methods and overall environment.
Choosing a school within a reasonable commuting distance will make it easier to attend consistently and free up time in your schedule throughout the academic year. The same considerations apply whether you're thinking about secondary schools in Galway or any other county in Ireland. Visiting schools in person, talking to students, and attending open days or information sessions can provide valuable insights to help you make an informed decision. It's also worth asking how each school supports students with different learning needs and interests.
- Check subject choices, examination performance and learning support.
- Consider school ethos, extracurricular activities and commuting distance.
- Visit schools and speak to students and staff before deciding.
How to Apply to Secondary Schools in Dublin
Before applying, read each school's published admissions policy and annual admissions notice. For the 2027/28 school year, the Department of Education asked schools to begin first-year admissions as early as possible in October 2026.¹ Check the application dates, available places and criteria used when a school receives more applications than it can accommodate. Living close to a school may be relevant under its admissions policy, but proximity doesn't automatically guarantee a place.
Every post-primary school must publish an admissions policy and an annual admissions notice outlining its application process and dates. Parents should check these documents carefully, particularly when a school receives more applications than it has available places. Schools must apply their published selection criteria fairly, and living nearby does not automatically guarantee admission.⁵
- Each school publishes its own admissions policy and application dates.
- Oversubscribed schools use published criteria to allocate places.
- Living near a school does not guarantee admission.
Finding the Best Dublin Secondary School for You
Start by shortlisting schools that offer the subjects and environment your child needs. Attend open days or information sessions to get a sense of each school. Check the Ireland school holidays when planning visits, as schools may be closed during the breaks. Where possible, speak with students and teachers before deciding which schools to apply to.
Take time to compare practical considerations such as travel, costs and admissions alongside your child's preferences. The school they attend will play a part in their education, but its ranking alone cannot guarantee academic success. If they need extra help with a particular subject or exam, a Superprof tutor can provide additional support.
- Shortlist schools based on individual needs, not rankings alone.
- Use open days and conversations with staff to make an informed choice.
- Additional tutoring can help students prepare for exams and build confidence.
