Proficiency Calculations Overview

Proficiency Calculations Overview

*Note: this is a district-only feature.

Your school or district can make one or more proficiency calculations available for you to use in your trackers. Read the following explanations to understand how scores are calculated and the interactions between them.

Most Recent

The mastery status is calculated based on the most recent assessment. This method is recommended for mastery learning or proficiency-based instruction.

Mode

The mastery status is calculated based on the most frequently achieved mastery level. In the case of a tie, the higher mastery level will determine proficiency status. For example, a student with R, NM, NM, M, M will result in M.

Maximum Value

The mastery status is calculated based on the highest mastery level achieved.

Decaying Average

This formula is calculated based on an average with more weight given to the most recent scores; the higher the decay rate, the more heavily recent assessments are weighted. Unless an administrator changes the decay weight, the most recent assessment is defaulted at 65% (the decay rate must be between 50% and 100%).

For example, if there are two assessments, the most recent assessment gets 65% weight, and the first gets 35%. For each additional assessment, the sum of the previous score calculations decay by an additional 35%. If you have three assessments, the weighting would be 12% for the first assessment, 23% for the second assessment, and 65% for the third assessment.

The math behind the 65% decaying average works like this; let's say you have four assessments that receive the following scores: `1`, `2`, `3`, `4` (this last one being the most recent):

`(1 × .35) + (2 × .65) = X``(X × .35) + (3 × .65) = Y``(Y × .35) + (4 × .65) = Z ` (this being the current standard score; 3.48)

Cut Scores—Your administrator may give you permission to change the decay rate and cut scores, which allows you to customize the range of the calculated value for each mastery level.

The following cut scores are recommended:

`  0—1.5 = `Remediation
`1.5—2.4 = `Near Mastery
`2.5—3.0 = `Mastery

Note: We do not recommend altering these cutoffs.

Average

An average of the proficiency levels (not scores) is calculated and used as the current mastery level.

Cut Scores—Your administrator may give you permission to change cut scores, which allows you to customize the range of the calculated value for each mastery level.

The following cut scores are recommended:

`  0—1.5 = `Remediation
`1.5—2.4 = `Near Mastery
`2.5—3.0 = `Mastery

Note: We do not recommend altering these cutoffs.

Power Law

The proficiency levels (not scores) are combined using power law to compute the current mastery level.

Note: Proficiency levels calculated using power law will be less accurate when a student’s performance doesn’t match the expected learning curve. For example, if the student's proficiency level is decreasing over time rather than increasing.

Cut Scores—Your administrator may give you permission to change cut scores, which allows you to customize the range of the calculated value for each mastery level. The following cut scores are recommended:

`  0—1.5 = `Remediation
`1.5—2.4 = `Near Mastery
`2.5—3.0 = `Mastery
