Dear Cammijc,

Thanks for your post. While this 'future' activity will certainly not be something that you list on the data forms or devote entire essays to, you may be able to work in a mention somewhere (in an interview, at the tail end of a relevant essay, etc). It's also possible that one of your recommenders might mention it as well (although I'd need a lot more information about your background, recommendation choices, etc to advise in that regard).

Of course, in order to mention it, it would be ideal to be able to honestly state that: a) you are already officially signed-up/enrolled in the project for next summer and b) that you will be doing this whether you get into b-school or not. While you might still be able to mention it in absence of these criteria - it starts to feel more like speculation at that point (like the applicant with a 65th percentile on the GMAT quant who claims that they "intend to pursue quantitative coursework in the spring if admitted to b-school").

Best of luck,

Graham
