Advertising on Exam Slips

A couple of years ago I noticed a link to a website called examzone on an edexcel gcse results slip.
Instantly I though ‘advertising’. Now I realise what a captive and open audience students receiving their results are, from resit colleges to iPads. Schools too, who print out a students results from all the exam boards on a single sheet of paper have a massive money making opportunity which I think they will realise before long, and start to use in this era of austerity. Every year when students take exams of any sort they will be issued with these results slips with paid for advertising.
My mind is running wild now. What about advertisements on school reports and letters to parents, certificates, school playing fields, school crests, the spelling and maths tests that students take regularly…
