A standard scientific calculator will be fine. A graphing calculator will not be necessary on any of the homework or exams in the pipeline. The math used in the program is taught assuming you are using a standard scientific calculator and is equivalent to advanced high school algebra, trigonometry and basic calculus. Graphing equations is of no interest to us.
As stated in a previous post, you may use a programmable calculator on homework if you prefer, but the use of a programmable calculator on exams is strictly prohibited due to the possibility of cheating. In my opinion it would be pointless to even have. Slide rules are still authorized, but are complicated and a little outdated.
On another note. Your daughter is entering a program that is very stressful. 12 hour days will begin to seem endless. Be sure to let her know that you support her and are proud of what she is doing. I know the support my family provided me while I was in the pipeline was very helpful in keeping me motivated and not discouraged.
Hope this helps! Good luck to you both!!
