In England, I've seen education get consistently more rigid and inflexible over the years. All about tests, tests and more tests. Teachers leave the profession, children turn off. And as it consistently fails to produce better results, the answer is always to do more of what has failed.
Bring something like this to England, please!
Clearly not the same as taking time off before university when you are already an adult though. Participation in some activities is required, so it's a bit more structured - and I don't think you can take off on your own to travel the world!
Many countries allow young people (under 30) to live and work in-country under a Working Holiday visa. Both are effectively Young People travelling (aka backpacking).
Transition Year is the 4th year of 2nd Level in Ireland - the conclusion of the 'Junior Cycle' of secondary school, culminating with the 10-14 Subject 'Junior Certificate' exam at the end of 3rd year. It is a regular year in terms of school attendance, but rather than academic modules structure against a strict curriculum, students tend to do a mix of practical and theoretical skills.
Things like intro to psychology, philosophy, an esoteric language or other college accession style intro classes are popular. Photography/Film Making, Cooking, Self-Defense/Martial Arts classes are all popular on the practical side.
Most of the religious schools (i.e. about 80% of all schools) tend to have a charity component as well - seeing TY students out collecting for Irish Cancer Society or packing bags in a supermarket to fund a local Hospice is pretty standard.
