Making the grade

 In Switzerland, declared Harry Lime in The Third Man, they had brotherly love, they had 500 years of democracy and peace, and what did they produce? The cuckoo clock. He would now surely have added the International Baccalaureate. There is no Swiss product which rates so highly with the British middle classes. Certainly not Nescafé, not in an age of filter machines. Not Emmental cheese and not Lindt chocolate.

The accepted wisdom is that while our own A levels have become watered down to the point of meaninglessness, the bac is still there to stretch pupils, just like in the good old days when schoolboys all wore blazers and caps and their masters flapped around dusty classrooms with gowns, mortarboards and canes.
The bac has spread far beyond the trendy private schools which began offering it 20 years ago. There are currently 149 state schools to offer it, with another 11 having applied to do so.
