Standards-aligned diagnostic Paths for K–12.
Find where learning breaks down.
SubjectPath's diagnostic Paths follow each student's answers back through a standards-based map to the skill where understanding stops, then build the path forward. Starting with Algebra Readiness.
The problem
A score tells you how far behind. Not where it broke.
Most assessments end with a number. A student who is behind might be missing one idea from two grades ago, or several. Knowing which one changes what happens next.
A typical result
“Below grade level in fractions.”
True, and not enough to act on.
What a SubjectPath diagnostic looks for
“Understanding breaks down at adding fractions with the same denominator.”
The skill where the gap starts, and the misconception behind the wrong answers.
How it works
Diagnose. Trace. Rebuild.
Diagnose
An adaptive diagnostic chooses each question based on the answers so far: a screener across the math domains, then follow-ups only where it finds possible gaps.
Trace
Answers are traced back through a prerequisite map of the standards to the skill where understanding breaks down. Each wrong answer is tagged to the misconception behind it.
Rebuild
Results feed a personal skill path: lessons and skill checks that rebuild from the break point forward.
