Boys, Girls and Grades: Details of the Academic Gender Balance Rating

For the purposes of this explanation, the indicators will be identified by a digit as follows:

  1. English 12: provincial examination mark
  2. English 12: percentage of provincial examinations failed
  3. English 12: difference between school mark and examination mark
  4. Mathematics 12: provincial examination mark
  5. Mathematics 12: percentage of provincial examinations failed
  6. Mathematics 12: difference between school mark and examination mark
  7. Graduation Rate

The Academic Gender Balance rating is derived as follows.

  1. For each school, for each year, six of the seven results were combined into four indicators, where I is the result identified by its subscript numeral, which refers to one of the seven indicators listed above.
  2. SUM(ABS(I1)+ABS(I4))
  3. SUM(ABS(I2)+ABS(I5))
  4. SUM(ABS(I3)+ABS(I6)).
  5. The absolute value of the Graduation Rate indicator ABS(I7) was calculated.
  6. For each of the four indicators produced by Step A above, the absolute values for the base year (school year 1992/1993) were sorted from lowest to highest and divided into groups of 10. Thus, 10 ranges of values were established (see below) and each range was assigned a score out of 10. Note that in all cases as the indicator gets higher--that is the school's performance deviates farther from gender balance--the score gets lower.
  7. The indicator values from all years are converted into a score out of 10 based on the range into which each falls. Note that in subsequent years, a school will get a score of 0 when its indicator value falls above the highest base year value contained in the range table.
  8. Finally, the four indicators are averaged to produce the overall Academic Gender Balance rating. Where less than four indicator values are available, no overall rating is calculated.

Indicator: value noted is the highest that will receive the range score listed.
