There are some opportunities for high school juniors who are level 9s, you usually just need to look for them yourselves. There also aren't athletic scholarships available for DII and III schools, so keep that in mind while searching.
Some DI teams are willing to take a level 9 IF they have an outstanding event, but those are also situations where you would need to really get your daughters name out there yourselves and it is becoming more and more rare with more girls choosing the NCAA route. But never say never! It is also not unheard of for Ivy League schools to take a solid level 9.
What part of the country are you in or where is your daughter looking to attend college? I strongly encourage her to look at schools first, gymnastics later. Many of the DII and DIII schools are smaller schools, so it's so important she finds one with the major she desires and at a cost your family can afford. Also, some of these teams I've heard just have open tryouts for newcomers early in the year, a place on the team isn't a sure thing until then. But it all depends on the school. Location also matters. Wisconsin and Minnesota have some DII and DIII schools, but they also have really big high school gymnastics programs providing them with solid level 9/10 range gymnasts. But, don't let that discourage you, it really does depend more on skills than a level number.
As for schools to look into, I don't know a ton of specifics but can give you some links and basic info.
I knew a girl who was on the team at Wilson College in Pennsylvania who was only a level 7. She was outstanding on beam though. It is, however, a VERY small school with limited offerings. They have an excellent equestrian program though if your daughter happens to be interested in that.
Ursinus College, near Philadelphia, is an EXCELLENT school academically. Very small, very pricey, but incredible. From what I have seen of their coach he seems really great and does a nice job with the team. One of their gymnasts was 1st AA at the Collegiate National Championships. They compete against many DI schools in the area and usually hold their own against them.
West Chester University, also near Philadelphia, has a DII team which also competes against some DI schools pretty regularly. The school has a good education program.
Rutgers in New Jersey has a DI program but they took one of my teammates who was a not very experienced level 10, so it could also be an option.
Here are some links with some links to schools:
