Once students have started Progress Monitoring using curriculum sampling CBM probes and have at least 3 probes completed, a trend line will appear on their graph.
Classworks determines the effectiveness of the intervention by taking into account the grade level of the CBM, the target rate of improvement, and the student results on the probes.
Their results can be viewed in one of two ways. You can generate their Progress Monitoring Results as explained here. Or, from the Progress Monitoring page, select the subject and click
When viewing the graph there are several things you should notice:
At the top, you can see the level, subject, and date range for the active CBM.
The connected purple dots show how the student scored on each week's probe.
The solid green line is the Target Rate of improvement for the 12-week duration. This is how much the student is expected to improve based on the current intervention. The target rate of improvement is determined by the goal that was selected: Moderate or Aggressive. This includes a number that shows the expected growth points each week (in this case, it is 4.5455 points per week for 12 weeks).
The yellow line is the Current Rate of Improvement and is calculated based on the student's weekly results and estimates which way the student is heading based on their current trend. This line is calculated using a "least-squares" regression equation and requires at least 3 results. This also includes a number to show you the student's actual growth (in this case, it is +5.0435).
The right-hand side of the table will show where the student is as far as Grade Level Readiness
The details of the Active progress monitoring session are the default view. If you wish to view other sessions, click the drop-down to select a date range.
First, the level, subject, and date range for the active CBM as well as a row for each of the 12 weeks.
The Date column indicates the CBM completion date. It says Skipped if the student skipped (missed a week) or is blank if it is an upcoming week.
The amount of time the student spent taking the CBM.
Their score for each week taken.
Any notes that might have been recorded for a given week.
Cumulative Item Responses
Below the graph and weekly details, you will find the Cumulative Item Response table. This table breaks down which domains the student was tested on, and how well they did.
For example, in the table below, we can see that this student was presented with 3 questions on Measurement for week one, and they got 1 out of those 3 questions correct. In week 5, they got 2 out of 3 of those questions correct, and so forth. In the far right column, you will see a “grand total” of how the student has done in each domain so far (ie. between weeks 1 and 8, this student has gotten 8 out of 12 questions correct for Measurement).
