Hi
I employed an electrical apprentice last year and hopefully will another this year. I also recruit university level placement students. Congratulations to your brother on his marks, and a driving license is indeed a good differentiator. Encourage your brother to find a way to put on his application that his marks were so good compared to his peers "top 10% of class" something like that. Dont be afraid of using the number (ask college if necessary) - thats what will catch the eye and he needs to liven up his application.
Anyway what I look for is:
- Literacy, I bin applications with spelling and grammatical mistakes
- an interesting personal statement, so many 18 year olds just have nothing to say about themselves!
- a practical inclination eg model building or helping uncle John rewire Granny's house
Depending on his career plan, Id advise him not to neglect smaller companies. Outfits like British Rail that run the bigger apprentice schemes will have more competition because its easy for students to apply and 'their mate works there'
Good luck to him
