can you please explain the Irish medium schools please? They are similar to private but free is the jist I'm getting?
@Kateforqueen
I suspect your question is based on assumptions formed from observation of British education, in particular, the understanding that private = quality.
Ireland doesn't have the state vs private divide that the UK does. There are lots of excellent non-fee paying schools, and there is no stigma attached to attending them. As stated upthread, the vast majority of Irish schools are tuition free (there are registration fees and parents pay for books, supplies, and uniforms) and every school follows the same national curriculum in all subjects, with all students taking the same exams. All the teachers come from the same teacher training courses and have all come through the same education system.
In general, a wide range of parents of all income levels, educational background, and educational expectations send their children to whatever school is available in a reasonable radius of their home. Sometimes the school's location means an easy drop off en route to work. Sometimes parents want to send their child to the school they themselves attended. Sometimes they want to send their child to any school other than the one they attended.. A lot of parents pay attention to the academic reputation of the schools in their area and to schools' reputation for turmoil in the classrooms, etc.
In the case of a gaeilscoil, parents might be attracted by the Irish medium, the possibility of becoming part of an Irish speaking community based around the school, or the calibre of exam results. There is an extra layer to the parental school selection process because of the Irish language.
When parents choose a fee paying school, the reasons are often to do with academic reputation, though sometimes sports (rugby) or other extracurricular opportunities are factored in. Some parents are attracted by the vision of an old boy or old girl network and what this can mean for a child later in life. There is also family tradition, especially in the case of Loreto schools, the Jesuit schools, and Blackrock College. There are denominational factors too - CoI, Jewish, RC, or more secular preferences. Or a preference for a single sex school, though a huge number of non fee-paying schools are single sex. There are several all-girls' schools which consistently do extremely well in academic rankings. Fee paying schools sometimes offer a wider range of subjects for Leaving Cert than other schools,, for instance more MFLs, and the promise that students will be able to take whatever combination of subjects they want to, whereas they might be restricted to certain combinations in other schools.
