Knowing the Iowa Assessments (and the predecessor Iowa Tests of Basic Skills and Iowa Tests of Educational Development), the 75% should almost certainly be 75th percentile. This entire family of tests is all about percentiles rather than raw scores or what percent of questions you got right.
And the state of Iowa is actually a lovely place to live and is full of nice people. As it happens, I have an in-law who works for the company that puts out the Iowa Assessments - next Thursday I can short-change him on the size of his pumpkin pie slice if you'd like.
Best of luck,

Thank you for the percentile clarification about the test!
Also - both my parents grew up in Storm Lake, Iowa - I love it there! And, please let your relative eat all the pie he can get his hands on! It's not his fault that our school district is so test happy.
