My school (University of Oregon) had no connection between the bachelor's and master's. They graduated about 70 bachelor students, and took in 23 Masters students the year I went, so they couldn't really tie the two together.
A lot of us thought it should be a 3 year program--I took 17 grad credits per term for 8 terms, with 9 credits being considered full time. It was just crazy, and I can't say I'm not glad to be done. I have heard that some schools have tracks--you can choose medical or educational. Oregon required both, under the theory that your license would allow you to practice in either venue. I had to do both medical and school externships, but I know other slps who just did one.
It's a great field with a lot of opportunities. My whole class was employed long before graduation. Good luck to your daughter. My daughter is a sophomore in college and planning to be an slp as well.
**Just a tip for getting into grad school. I think having volunteer hours in the field is essential. I did hearing screenings for the local school district. I also had a professor tell me that in looking at applications, they strongly considered GRE verbal scores. This is all way down the road for your daughter, but the key is getting into grad school, since there are more people getting their undergrad in the field than there are slots in graduate school. Without the masters, you can get a job as an slpa, but not every school district allows them, and there aren't many medical opportunities at the bachelors level.
Edit to add: While most people have a BS in Communication Disorders, the other undergrad major you see a lot of is Linguistics with a few extra classes (such as Anatomy of Speech).
