Chances Mentoring provides primary and secondary education for pupils across Greater Manchester whose needs are not being met in mainstream settings.
Jane Turner is completing a level 3 teaching assistant apprenticeship and is one of the school's older apprentices.
She said: "Doing an apprenticeship as an older adult can feel challenging at times. I can feel different to the younger staff, but I also bring life experience to the role. I'm proud of learning something new, and that it's never too late to learn and grow."
Emily Lees, the school's first apprentice, completed her training last year, while Hammad Ali has finished his level 3 teaching assistant apprenticeship.
Louise Taylor is studying for a level 3 teaching assistant qualification with a SEND specialism and Ronnie Watson started a business administration apprenticeship this month.
Callum Siddall, founder and director of Chances Mentoring, said: "Investing in our team is how we make sure our young people get the support they need. Apprenticeships let staff learn while they work, so what they study goes straight into the classroom.
"Several of the people qualifying this year started with us in support roles and are now building professional careers here. Apprenticeship routes suit our workforce, because the job needs practical experience alongside formal training."
The school said developing staff internally reduces its reliance on external recruitment and helps maintain its therapeutic approach to education.
It also said Ofsted rated it a strong standard for inclusion in March this year.
