6i Lens · K-12 instructional practice

Built by a teacher who never left the classroom.

Diagnose Develop Sustain

Between what a student is taught and what they actually understand sits a space no score report is built to show. 6i Lens makes that space visible, names what caused it, and hands you the move that closes it.

One method, running across the whole school day, from the diagnostic to the door.

What we do

A diagnostic that names the misconception,
and six tools that act on it.

6i Lens takes the work students already do and hands back the standard, the item, and the specific misconception behind a wrong answer. It reads two scores where most reports read one: what a student can pick off a multiple-choice list, and what the same student can build from scratch. On 6.EE.7, 66% of sixth graders pick the right equation and 31% can write one. That 35-point drop is the part a proficiency band hides. From there the same diagnosis follows the student through the day, into practice with a tutor that asks for their reasoning instead of handing over the answer, and into the schedule, the attendance, and the walkthrough.

The lens

Standard testing shows you a score.
6i Lens shows you the spot.

On 6.EE.7, 66% of sixth graders pick the correct equation off a multiple-choice list. Only 31% can write one from a story. That 35-point drop is the largest constructed-response gap in sixth grade, and it never shows up on a proficiency report. Move the lens across the panel below.

Move your cursor over the panel. On touch, tap to sweep the lens across.

About these numbers. The flagged cell, 6.EE.7, carries the 6i canonical sixth-grade figure: 66% on multiple choice against 31% on constructed response. The seven cells around it are sample values, there to build the wall a score report actually hands you.

The practice

One lens, three moves.

Most students don't struggle because they can't do the work. They come apart at a specific point where content meets concept. The three moves below find that point, act on it, and keep it from reopening.

01
Diagnose

See exactly where it breaks.

You get the standard, the item, and the specific misconception behind a wrong answer, instead of a grade-level label you can't teach from.

02
Develop

Reach for the right move.

The canonical strategy, the bridge, the manipulative, matched to the break you just found. Students meet it as an AI tutor that will not hand over the answer and asks for their reasoning instead, so practice produces the very thinking the diagnostic reads.

03
Sustain

Make the gain hold.

The practice and the tools run off the same method, so a fix made in October still holds in May, across a classroom, a grade, and a school.

Who it's for

One lens. Three ways to use it.

The same diagnostic data answers three different first questions, depending on where you sit: the district office, the building, or the room itself.

District & instructional leadership

See the collapse before it's a headline.

One diagnosis rolls up from item to classroom to school to district, so a curriculum decision rests on where students actually break, not on a proficiency band.

Principals & instructional coaches

Walk into a room already knowing where to look.

Rounds and the diagnostic data share one method, so a walkthrough finds the same gap a test already flagged, instead of two separate stories about the same classroom.

Teachers

Get the next move, not just the score.

A wrong answer comes back with the standard, the misconception, and the strategy that closes it, so a Tuesday planning period is spent teaching, not decoding a report.

The evidence
Every number on this page traces to a source. If it can't be sourced, it doesn't go on the page.
The 6i Lens methodThirteen years of hands-on work with New York State's released test items and the score data attached to them, paired with eighteen years teaching the students those items were written for.
01

Sourced, not invented.

Every p-value and every flagged misconception traces back to a released item or a documented classroom pattern. The 6.EE.7 gap above is the canonical example, not an outlier picked because it looks dramatic.

02

A named taxonomy of errors.

A wrong answer isn't just marked wrong. It maps to a documented misconception, so "reteach fractions" becomes the exact breakdown behind this student's answer on this standard.

03

Tested against real classrooms first.

Every framework here, Diagnose, Develop, Sustain, was worked out with real students and real state data before any of it became software.

Questions

What people ask before they start.

Does 6i Lens replace our curriculum or benchmark tests?+

No. It sits alongside what you already run. The diagnostic finds the exact standard and misconception behind a score; your curriculum and your benchmark stay in place. 6i Lens tells you where to aim them.

How is this different from a universal screener we already use?+

Most screeners hand back a proficiency band. 6i Lens hands back the standard, the item, and the specific misconception, and it distinguishes a multiple-choice score from a constructed-response one. That gap, not the average, is usually where the real problem lives.

What happens to student data?+

Every 6i Lens app runs against a written privacy policy, FERPA notice, and data privacy agreement template, published in full and outside any login wall. Read the Privacy Policy, the FERPA Notice, or the full set at diagnostics.6i-lens.com/legal before you sign anything.

How is 6i Lens priced?+

Pricing is scoped to the grade bands and schools you're bringing in, not a flat rate. Start a conversation and we'll work out a number together.

What does getting started actually look like?+

There's no fixed rollout script. A conversation figures out which app you start with, which grade bands come first, and what your calendar can actually hold, before anything gets scheduled.
