Achievement
Evaluation
Achievement
evaluation is based upon a comparison of Current Year data to a set of
standards which remain consistent over time. The Standards are
calculated by taking the 3 year average of baseline data for each
measure across all school jurisdictions and calculating the 5th, 25th,
75th and 95th percentiles. Once calculated, these standards remain in
place from year to year to allow for consistent planning and
evaluation.
The table
below shows the range of values defining the 5 achievement evaluation
levels for each measure.

Notes:
1) For
all measures except Drop Out Rate: The range of values at each
evaluation level is interpreted as “greater than or equal to" the "Low"
value, and "less than" the "High" value. For the Very High category,
values range from greater than the "Low" value to 100%.
2) Drop
Out Rate measure: As "Drop-out Rate" is inverse to most measures (i.e.
Lower values are "better"), the range of values at each evaluation
level is interpreted as "greater than" the "Low" value and "less than
or equal to" the "High" value. For the Very High category, values range
from 0% to less than or equal to the "High" value.
Improvement
Table
For each
jurisdiction, improvement evaluation consists of comparing the Current
Year result for each measure with the previous three-year average. A
chi-square statistical test is used to determine the significance of
the improvement. This test takes into account the size of the
jurisdiction in the calculation to make improvement evaluation fair
across jurisdictions of different sizes.
The table
below shows the definition of the 5 improvement evaluation levels based
upon the chi-square result.

Overall

The
overall evaluation combines the Achievement Evaluation and the
Improvement Evaluation. The table below illustrates how the Achievement

Category
Evaluation
The
category evaluation is an average of the Overall Evaluation of the
measures that make up the category. For the purpose of the calculation,
consider an Overall Evaluation of Excellent to be 2, Good to be 1,
Acceptable to be 0, Issue to be -1, and Concern to be -2. The simple
average (mean) of these values rounded to the nearest integer produces
the Category Evaluation value. This is converted back to a colour using
the same scale above (e.g. 2=Excellent, 1=Good, 0=Intermediate,
-1=Issue, -2=Concern).
