"This is Sweden's biggest fair when it comes to audience," says Alexander Vasiliou, co-founder of Dansgymnasiet, which offers an upper secondary education based around dance.
At his stall, two of his teachers put on regular performances to a background of thumping techno.
It's a huge contrast to the stalls for Stockholm's biggest municipality-run schools, which are arranged in a square in the centre of the room, all of the sporting the same simple orange logos.
Jakob Durling, a teacher who is attending the fair with his students from Kista International School, is convinced it is good for both private and municipal schools.
"It's a wake-up call for the muncipal schools to do a bit of PR," he says. "They have to wake up and see what the private schools are doing."
