Dallas — Cross-Subject Insight

The finding that reframes the whole conversation

91 students are scored as a math problem —
but the data says they have a writing problem.

That's about 1 in 10 of every math test taker. No single-subject report can see this, because it only exists when you read the Math and ELA files for the same student at once.

The Expression Gap

They can do the math. They can't put the reasoning into words.

These 91 students answer multiple-choice math correctly, then collapse on the open-response items that ask them to explain — and every one of them is also flagged Low on the ELA Text-Dependent-Analysis essay. The math score is a symptom. The cause is written expression.

How we know: for each student we compare multiple-choice vs. open-response raw performance within the math test, then join to that same student's ELA reporting categories. A large MC–OE gap that co-occurs with a Low Text-Dependent-Analysis flag is the signature of an expression gap, not a content gap. What to do: writing-across-the-content-areas support and constructed-response practice — not more math remediation. Spending intervention dollars on these students as "math kids" is spending them in the wrong subject.

One Standard Away

17 students are a single standard from Proficient. Here's the roster.

Of 408 students sitting at Basic in math, 17 are held back by exactly one weak standard. That isn't a vague "needs support" list — it's a specific set of small groups a principal can schedule Monday.

The one standard they need	Students	Small groups	Where (top buildings)
A-FNumbers & Operations—Fractions Understand, compare, and compute with fractions.	6	1 group	Dallas Intermediate School (6)
C-GGeometry Shapes, angles, area, surface area, volume, and the coordinate plane.	3	1 group	Dallas Middle School (2), Dallas Intermediate School (1)

District math proficiency if these 17 single-standard students cross the line — reachable with 9 targeted small groups, not a district-wide program.

How we know: we take every student scored Basic in math, count their Low reporting-category flags, and isolate those with exactly one. Each maps to a single eligible-content standard and a home building — so the intervention is a named group, sized, and located. Why it matters: the cheapest proficiency points in any district are the students already almost there. This finds them by name and tells you the one thing each needs.
