Dear student,
I have received your request for information concerning the reporting of
marks for the School Certificate tests. The following explanation should
help you:
******************************
School Certificate (SC) Test Marks
For each of the five SC tests is a document known as the "Performance Band
Descriptions". This document describes different levels of performance in
the Test. The highest level of performance is known as Band 6, then Band 5,
Band 4, Band 3, Band 2 and Band 1. Each of these bands (other than the
lowest band: Band 1) has a description of performance describing the
knowledge and skills that students have at that level. Student marks are
reported in relation to these bands. If you would like to view these
Descriptions for each test, please look at the Board of Studies website at
the following location:
http://www.boardofstudies.nsw.edu.au/schoolcertificate/sc_pbd.html
Once students have completed the test, then all questions are marked. For
each question or item in the examination a raw mark is calculated; this is
the value out of which the question is marked. All of these marks are then
added up across the examination to form a student's Total Weighted Mark
(TWM).
To determine the performance band a student has achieved, a group of judges
considers each question in the test and decides what marks students at the
borderline between each of the performance bands would be likely to
achieve. This is a lengthy process that involves a review of the
performance descriptors, statistical feedback, and consideration of
students' scripts. Once this is complete the judges will have determined
which TWMs correspond to the borders between each of the performance bands.
For example, it may be determined that a TWM of say 82 is the minimum
required to get into Band 6, 74 for Band 5, and so on.
The TWM is converted to a Test Mark (TM, also known as an aligned mark),
which is the final test mark for the course. The TM is calculated by
mapping the TWM to the performance band cut-offs. For example, if the
cut-off for getting into Band 6 has been determined as 82, then all
students that have received a TWM of 82 would get a TM of 90. If the cutoff
for Band 5 has been determined as 74, then all students with a TWM of 74
would get a TM of 80. The cut offs for Band 4, and Band 3, Band 2 and Band
1 are mapped to 70, 60, 50 and 0 respectively. TWMs that do not fall at the
cut offs are adjusted accordingly using linear interpolation. Finally, for
statistical and measurement purposes, a committee of experts review the
entire process for the course and determine any minor adjustments that may
need to be made to the top and bottom marks for the course or to the
performance band cut offs.
******************************
So, you can see that the test mark is not divided by two and added to 50.
Indeed, it is possible to get a mark less than fifty; all students that are
not as good as Band 2 (that is, are in Band 1) receive a mark that is less
than 50.
If you are interested, you can also see on our website the percentages of
students that received each band in previous School Certificate years, for
each test. For this information, please see the following page on our
website:
http://www.boardofstudies.nsw.edu.au/ebos/static/BDSC_2004_10.htm
For example, in 2004, 2.76% of students in the English-literacy test
received a reported mark of less than 50; these were the students in Band
1. However, the vast majority of students were able to gain at least a Band
2 result.
I hope that this information has helped you in your understanding of the
reporting for the SC test. If you have any further questions, please reply
to my email.
