Standards Mastery by Student
Each cell shows whether a student has mastered (✓), approached (~), or not met (✗) the standard. Gray cells indicate the standard has not yet been assessed for that student. Level 3 = mastered.
Testlet Details
For each testlet completed by the class, the distribution of student performance levels and the standards assessed. Level 3 indicates mastery.
Growth Report
Mastery Growth Index analysis showing ability change and content mastery across the classroom.
Understanding Pace & Trajectory
Pace reflects testlet mastery: how much content a student has mastered so far, like a speedometer showing current speed. Students already at high pace have mastered most content and have limited room to go faster. Trajectory reflects ability change over time: whether a student's measured ability is increasing, steady, or decreasing. A rising trajectory means the student is accelerating their learning. Together, these two dimensions give a fuller picture. A student at high pace but flat trajectory is maintaining strong performance, while a student at lower pace but rising trajectory is catching up.

Growth v2 Report
Split-minimum MGI: mastery contributes from testlet 3, ability growth from testlet 6.
How Growth v2 Works
This report uses a split-minimum approach to the Mastery Growth Index. Rather than requiring a single minimum number of testlets for the full MGI, each component activates independently: content mastery (Pace) begins contributing to MGI once a student completes their 3rd testlet, while ability growth (Trajectory) begins contributing once the 6th testlet is completed. Before each threshold, that component is treated as zero. This gives earlier, partial growth signals — teachers can see mastery trends by testlet 3 without waiting for enough data to measure ability change.
Split-Minimum MGI Formula
Each component of the Mastery Growth Index activates at a different point in the year.
Content Mastery Component
Active from testlet 3. Counts standards mastered out of 12 total.

Ability Growth Component
Active from testlet 6. Compares early ability to current ability estimate.

MGI Explorer
2D view of student ability growth vs. mastery rate with adjustable weighting.
About the MGI Explorer
This tool lets you explore how the two components of the Mastery Growth Index (ability growth and content mastery) interact. Use the weight slider to adjust how much each component contributes to MGI. Changes made here apply across all tabs: adjusting the weighting will recalculate MGI scores, shift the diagonal category boundaries, and update every chart and table in the report.

Mastery
50%
MGI = 50% × Ability Growth + 50% × Mastery Rate (Mastered / 12). Changing the weight shifts the diagonal category boundaries and recalculates MGI values.

MGI Bar Ranking
Students ranked by composite MGI score. Bar length = MGI value, color = growth category.
Mastery Clock
12 slices (one per testlet) fill when mastered. A spiral line from 12 o'clock traces cumulative MGI, spiraling outward as growth accumulates.

Growth–Forecast Triangle
MGI (x-axis) vs distance from proficiency (y-axis). Three zones: On Track (green), Growing but Behind (yellow), Urgent (red). The hypotenuse connects max growth to max proficiency.
Mastery Clock — Ability Trajectory
Same mastery pie, but the spiral traces ability change (θ − Early θ) over time instead of MGI. Outward = more growth from baseline.

Mastery Clock — Concentric Rings
Same mastery pie, but instead of a spiral line, each completed testlet places a concentric circle at the ability change value on the radial scale.

Growth Sufficiency
Current scale score → projected EOY score for each student. The dashed line marks the proficiency cut. Arrow color shows whether the student's current growth rate is sufficient to reach proficiency.
Performance × Knowledge Growth
Ability change line (performance — "getting better at math") overlaid on stacked testlet bars (knowledge — "learning new math"). Each bar = one testlet's mastery status.

MGI Sufficiency — Is Each Student Growing Fast Enough?
X-axis = current ability estimate (scale score). Y-axis = Mastery Growth Index (MGI). Each dot shows a student's current position and growth. The arrow shows how far they've moved from their early score — curvature indicates acceleration or deceleration. Green = on pace to reach next proficiency tier; red = below required pace. Hover a student to see their individual growth goal.
This chart answers three questions at once: Where is the student now? How fast are they growing? Is that fast enough?

2. Tier Transitions
Where did students in each starting tier end up? Flow widths show how many students moved between performance levels. Upward flows (lighter colors) represent growth; downward flows (darker colors) represent regression. This is the clearest answer to "did our instruction move students to higher tiers?"
Available from testlet 3. Most meaningful at testlet 12 (summative).
3. Achievement Matrix
A 4×4 grid crossing starting tier (rows) with current achievement level (columns). Cell color intensity shows student density. The diagonal represents students who maintained their level. Cells right of the diagonal = growth; cells left = regression. This immediately highlights which starting groups moved and where they went.
