College Confidential has an athletic recruit board that might be helpful to you. My DS was a swimmer at a top LAC which was D3. No $$ because it was a need based school, but a "tip" from a coach can help with admission. Head over to College Confidential. People are very helpful.

Lacrosse is a sport where most scholarships are split. You get a fraction of the total cost, even at D1. If money is an object you may look further down the food chain to a D2 or D3 school if the player has good grades and scores. May work out to be less costly.

You can usually find the number of total scholarships available for each team. Those are then divided up among the recruits. in state at UMD without a scholarship may be cheaper so don't rule that out.

NP: I am also interested for my DD who is a swimmer. She does not have the times for serious college interest but I am curious.

DS is a defense lacrosse player. His Club and HS coach believe he will be a Div 1 recruit. Unfortunately he has not had interest from University of MD so that we could pay in-state tuition.

what sport? what position?

Depends on how good your DS is, how much they want him, what school, and what funds are available.

I am just wondering what is realistic if DS is recruited to play A Division 1 Sport. We won't qualify for financial aid an have limited available income since we support a family member with special needs. The numbers look good in paper only. Is there usually a significant scholarship which comes with Div 1 offer?
