PLEASE view the interview by the Ministry of Education on the process of how students are placed. Even if your child makes the composite score for a school, there may be a chance that places in the school were filled with children whose first choice was that school and/or composite score was higher, before your child’s composite score was reached.

### SEA 2019 Cut Off Scores

Calculating the Weighted Composite Scores for SEA:

Firstly the student’s standard scores are calculated for Math, ELA and CW. This is done by using the formula:

100 + 15 Zi    where,

Zi = Xi – x / S

Zi =xi – x / S

In order to calculate Zi, the following values must be known:

xi = student’s individual raw score

x = the population mean for the subject area (which changes every year and is different for each subject area)
S = the standard deviation for the subject area (which changes every year and is different for each subject area)

So, a standard score is calculated for Math, ELA and CW. Then, the scores are weighted as follows:
Math wt = 100% of the calculated Math standard score

ELA wt = 60% of the calculated ELA standard score

CW wt = 40% of the calculated CW (ie, the ELA writing) standard score.

The weighted composite score = Maths wt + ELA wt + CW wt

Using fictitious values for the “Means” and “Standard deviations” we have examples of how the composite scores are calculated.  Categories:
