The school is one of more than 500 across Britain registered with the charity Future First to set up networks of former students or alumni.
Nationally more than 50,000 former students have already signed up to stay connected with their old school.
They inspire young people in a number of ways - as career and education role models, mentors or e-mentors, work experience providers, governors, donors or fundraisers.
It doesn’t matter when they left school, whether they are in further education or employment, whether they still live nearby or have moved further away.
Future First managing director Alex Shapland-Howes said: “More than 39 per cent of state school students don’t know anyone in a job they’d like to do,.
“If they see that someone who went to the same school, grew up in the same community, has achieved a fulfilling and satisfying job, it helps them see it’s possible for them too.
“It’s really important for all students to be motivated to succeed in the working world and hearing first hand from relatable people in interesting jobs can make a huge difference.”
