England mostly doesn't (though there's some local variation). Most secondary (11-16/18) schools are 'comprehensive', covering the full range of abilities. It is standard to set pupils by ability in most subjects, but uncommon to track/stream pupils by general ability across the whole curriculum. We previously ran a split system, with exams splitting pupils at 11 into academic ('grammar') and non-academic ('secondary modern') schools. Many grammar schools were good; most sec mods were awful. The exams also famously had pretty poor predictive power for underlying academic ability as an adult, so pathways had to be developed to allow bright pupils to go to higher education despite being mis-sorted in the original exam - which somewhat undermines the point of the system. Comprehensivisation has never been nationally mandated, but nearly all areas have now done away with academic selection at 11. The remaining holdouts are mostly suburban Conservative areas where political power is in the hands of the well-heeled upper middle classes who are strongly in favour of grammars (and expect their own children to go there). Interestingly, Margaret Thatcher (as Education Secretary under Heath) was responsible for more grammar school closures than Labour was. Vocational/academic choices are now being made at age 14 and 16 either within the secondary schools or by moving to local further education colleges (similar to US community colleges and trade schools). Vocational classes are low status. Britain no longer has a strong industrial sector to use such skills, and although both parties advocate for better vocational education essentially everyone who matters would be most unhappy if their darling children were diverted from a university track in the direction of trades. That's something they want other (poorer) people's children to do, not their own. We've never developed good vocational training for offices/services jobs, and although such courses do exist they're not taken particularly seriously by employers, despite several rounds of national reforms.
