Curriculum Sampling probes are scored using the Universal Screener Scaled Scores and Domain-based probes are scored using percentages.
Scoring of Domain-based Probes
Look at the sample graph below:
- Baseline Determined: The median of the student's first three probes determines the starting point
In this example the median of the first 3 probes was 23%. That is where the green (Target Rate of Improvement) and yellow (student's actual Rate of Improvement) lines begin.
- Target Rate of Improvement: This is determined by the type of goal the teacher selected In this example the teacher selected an Aggressive goal
- Moderate - 70% goal by the end of 12 weeks
- Aggressive - 80% goal by the end of 12 weeks
- Moderate/Aggressive ROI: Classworks calculates the trend line using an ordinary least squares regression equation. (A constant slope from baseline to the goal)
In this example the Target Rate of Improvement is a constant sloped line from 23% (the child's baseline) and 80% the Aggressive Goal. The student needs to improve 5.1818% each week to reach this goal.
- Student Rate of Improvement: How many percentage points the student needs to improve weekly to reach the 12-week goal
In this example the student is currently improving their weekly score by an average of 4.2518%. The student is performing below the target needed to reach their goal.
Scoring of Curriculum Sampling Probes
Look at the sample graph below:
- Baseline Determined: The median of the student's first three probes determines the starting point
In this example the median of the first 3 probes was 220 That is where the green (Target Rate of Improvement) and yellow (student's actual Rate of Improvement) lines begin.
- Target Rate of Improvement: This is determined by the type of goal the teacher selected In this example the teacher selected a Moderate goal
- Moderate - Score at or above the next assessment target (Make 18 weeks of growth in 12 weeks)
- Aggressive - Score at or above the second next assessment target (Make 36 weeks of growth in 12 weeks)
- Moderate/Aggressive ROI: Classworks calculates the trend line using an ordinary least squares regression equation. (A constant slope from baseline to the goal)
In this example the Target Rate of Improvement is a constant sloped line from 220 (the child's baseline) and 240 the Moderate Goal. The student needs to improve 0.9091 each week to reach this goal.
- Student Rate of Improvement: How many percentage points the student needs to improve weekly to reach the 12-week goal
In this example the student is currently improving their weekly score by an average of 3.3631. The student is performing on target to reach their goal.
