how do i know what i need to score?

Hello, i wanted to know how the scoring for the teas test worked i was given a sample sheet for the scores that i need to receive in order to get into the program. They go as followed:

Adjusted Individual Total Score: 90.0%

Mean-National: 74.1%

Mean Program: 75.2

Percentile Rank-National-blank

Percentile Rank-Program-blank

(Scores noted in Admission Greater than or equal to 45th percentile)

TEAS: Reading 97.5% 86.4% 87.7% 97 96

TEAS: Math 86.7% 63.7% 64.6% 92 92

TEAS: Science 86.7% 66.9% 67.9% 96 96

TEAS: English 90.9% 77.8% 78.8% 95 95

The directions as to what they require are "Student applicants must achieve a minimum score of 45 reflected under the "Program Percentile Rank" in each category of the test. Reading Math Science and English.

What I'm trying to figure out, is what the 45th percentile means as to what i need to score.. if anyone can help I would really appreciate it (:
