No, FieldLevel is a free social network. You can maintain your profile and be found by college recruiters for free. Your profile may also be promoted to college recruiters for free, which is the most effective way to gain the attention of college recruiters.
However, you can activate a premium account that requires a monthly subscription fee. A premium account shows you exactly which college programs are recruiting your position and what their interest is in you. Once activated, charges occur automatically each month. After a charge has been incurred, it cannot be removed retroactively.
