Prior to 2012, NCAA rules did not allow its member schools to award any type of athletic scholarship other than on a 1 year renewable basis. Schools offered 4 year scholarships (5th year with a redshirt) but the 4 year period was not guaranteed. This all changed in 2012 when the member schools voted to allow 4 year "guaranteed" scholarships to be offered. It was left to the discretion of the schools as to what type of scholarships they would offer. But, if they decided to offer 4 year guaranteed scholarship, they had to offer it to all sports. They could not offer a 4 year guaranteed scholarship for football and not offer the same for softball. The 2012 vote was very contentious. Some schools (Alabama and LSU being at the forefront) opposed multiyear scholarships because they said that it could reduce the flexibility of a new coach to get rid of players who didn't fit his style. Most people to this day, and not enough college recruits, don't realize is that a university can yank that scholarship after one, two, or three years without any cause if the scholarship is not a 4 year guaranteed one. However, most schools will not do this (at least not on a frequent basis) because of the hit they would take on the recruiting trail.
I would venture to say that UL is not offering 4 year guaranteed scholarships to its student athletes and is instead offering 1 year renewable scholarships. I do know that majority of the schools in the Big 10 now only offer 4 year guaranteed scholarships and use this as a selling tool when recruiting a student athlete. If you have a child that is currently being recruited, you might want to ask the school what type of scholarship are they offering.
