This year, Chapman's first year students range from 20 year old international students to 35 year old screenwriters. I'm a 32 year old director. There's a wide spread here. There's at least one student further along and nearing their 40s that I've met.
Statistically, the average age of an MFA student is late 20s, but as you can see there's a lot of range as both Kira and I have experienced.
