A low ACT does not equal a low TEAS score. They are formatted differently and they cover slightly different content. I score a 22 on the ACT and a 70.7 on the TEAS V. 22 / 36 = 61%, so I actually did better on the TEAS. I will say that a 13 is about 5 points below the national average. An 18 on the ACT is 50%. She will need to do some remediation courses in math and English in order to score well on the TEAS V. The math is a lot easier on the TEAS. I thought the Verbal skill portions were about the same only the TEAS requires you to pick information our of charts/graphs where the ACT is just reading. The TEAS science section is 10 fold harder, but they ask the kind of questions that your either do or don't know (for the most part.) Another thing is that I didn't feel rushed for time when I took the TEAS V.
