There are several different levels of interest that a college coach can show in a player. Based on the level of contact they have with you, you should be able to get a rough idea of how serious they are about offering you a scholarship. These levels are by no means fixed (different schools do things in different ways) but the general idea is that the more often and the more personal contact they create the more serious they are about you. Below is one example:
Noticed:
Mailed you a questionnaire to fill out and return.
Mailed you a summer camp application.
Put you on the school’s general mailing list.
Interested:
All the above plus…
Called and spoke with your club coach/club director.
Emailing you on a consistent basis.
If possible they will come to see you play.
Mailed you a package with media guide, school info, an other general goodies.
Sending you regular mail directly from the Athletic Department.
Very Interested:
All the above plus…
Make a effort to see you play on several occasions.
Setting up a phone call for you to call them (Notably for NCAA due to contact rules).
Invite you to tryouts at the beginning of your first semester. (Many CIS schools)
Committed:
All the above plus…
Sets up regular phone calls for you to contact them.
Concretely offers you a scholarship. (verbally and or in writing)
Invites you for to make an “official” or ”unofficial” visit to the school.
