In easyCBM we don’t have specific probes targeting Math Problem Solving because the standards (CCSS and most state-based systems that mirror the CCSS) moved away from skill-based standards (e.g., application, computation, problem-solving), deciding to embed those skills across grade-level math domains (e.g., geometry, measurement, etc). *Note: If you are referencing the detailed tables, there are remnants of older assessments (i.e., appl = application; comp = computation) that are no longer available as of a few years ago given the move to benchmarks/probes aligned with the National Council of Teachers of Mathematics (NCTM) Focal Points Standards and the CCSS.

Here is what our easyCBM recommendation would be:

1. If the student is functioning close to grade-level expectations (i.e., based on CCSS benchmarking and other classroom-based data/information) then the CCSS probes would likely be most appropriate. They are longer (25-30 problems) and more difficult than the NCTM measures, but include applications of math reasoning and multiple problem solving items in each probe. I’m looking at and thinking about Grades 6-8 here.

2. If the student is functioning below his/her enrolled grade-level expectations (below 6th grade?), then one of the NCTM Focal Point probes (just 16 test problems) is likely more appropriate — at Grade 6, the Algebra probes have the most problem solving/applied reasoning type problems in them.

*far below*grade-level expectations, we suggest working with the teacher/school psych/etc to actually look at the math problems in prior grade-level probes (i.e., Grade 5 would include: Nums and Ops, Gmtry Msrmnt and Algebra, and Nums Ops and Algebra…… and then the CCSS Math probes). By looking at the actual test items, which should be similar in style across each of the ten test forms/and within each probe type you would be working to match what the student is being taught (generally, but more importantly, during intervention support), to the most appropriate probe(s). If unsure which one, benchmark performance might help identify areas/problem types of weakness.
