They ought to show intended outcomes and how they'll assess program effectiveness, but this is akin to asking a fetus to prove it's going to become a grown adult prior to it being born and, you know, growing up. Holding a grant recipient accountable is a must but if a program needs grant money to get itself started, it needs it. It doesn't sound realistic to necessarily show results before a program has started. Again, you need to show intentions and a plan of action, and follow up afterwards.
