NCAA scholarships are for one year only. They are renewed (or not) on an annual basis. Any thing promised beyond the first year is between the student and the school. Some athletic conferences have agreed to offer 4 year scholarships (e.g. P5 conferences). Some schools may offer more than one year on their own--just understand that anything beyond that first year at those school is not guaranteed unless you somehow get something in writing from the school. Should that coach get fired or take another job and you don't have something in writing from the school--good luck getting the school to honor that coach's verbal offer.
This is exactly why the NCAA had to alter the rules for the 2020/2021 academic year. Schools had to honor the NLI's signed by incoming freshman which meant they would likely exceed the 11.7/27 rule. So they increased it to 11.7/32 and dropped the 25% minimum (D1). That meant some returning players could have received less money than they received in prior years. This is why the ruling occurred prior to coaches having to renew the NCAA annual scholarships for their players.
