Strategic StudentIs this intervention working?
You started an intervention and you're collecting weekly scores. Type them in and get an instant graph with an aimline, a trendline, and a clear answer about whether the plan is on pace. No PII. No login. Everything runs in your browser.

Enter a goal score and at least one weekly score above. We'll draw the aimline, fit the trendline, and tell you what the pattern says.
The graph
Weekly scores against the aimline.
Keep in mind
- Wait for six or more points before making big decisions. Early points bounce around, and three is the bare minimum to see anything at all.
- Same measure, same conditions, same duration every week, so the points stay comparable. A two-minute probe on Monday isn't the same as a one-minute probe on Friday.
- A flat week is data, not failure. Patterns beat single points every time, so chart the week and keep going.
How this works
The aimline is the pace line. It starts at the first score and runs in a straight line to the goal by the week you picked. The trendline is what the student is really doing: the one straight line that fits the entered scores as closely as possible. When the trendline moves toward the goal as fast as the aimline or faster, the plan is on pace. If the goal sits below the first score, the grapher treats lower as better (office referrals, errors, minutes off task) and reads every comparison in that direction.
The four-point rule comes from data-based individualization practice. Four consecutive points on the goal side of the aimline means the student is outrunning the goal, so raise it. Four consecutive points on the other side means the current plan is not closing the gap, so change something about the intervention before changing anything about the goal. The four-point rule waits until six points are charted; before that, the verdict is an early read from the trendline alone.
NCII's usual baseline is the median of three probes; this grapher starts from your first score, so enter a median as the first number if you have three baseline probes. Weeks you skipped can be typed as x so the trendline is fit on the real calendar, and the projected score is simply the trendline carried out to the goal week.
The trendline is an ordinary least-squares fit, which is just the math for drawing the single straight line that sits closest to all of your points at once.

This graph decides whether the intervention is working, never whether the student is. When the line is flat, change what we're doing, not how we see the student.
