OXTED School pupil Owen Thurston attended an event at the House of Commons on March 24, to launch Young Epilepsy's Manifesto for Change.
The campaign aims to ensure all young people with epilepsy get the help they need at school to reach their full potential.
The 15-year-old has worked with the Lingfield-based Young Epilepsy charity since 2012, when he took part in a research project for them.
Last year, he was nominated for a Young Epilepsy Champion's Award after he addressed a Freemasons' event and received a cheque on behalf of the charity.
