Which of these concerns is determined on the K-12 level?

how to appropriately test students

how to ensure students are ready for jobs

how to fund the growing cost of tuition

how to pay for higher-education research

One of the concerns determined on the K-12 level is how to appropriately test students.

Since K-12 refers to primary (and sometimes secondary education), the second option is too soon to consider. K-12 has to do with teaching and learning, so C and D are also incorrect.
