The <strong>High</strong>er <strong>School</strong>CertificatePoints to noteFrom a stat<strong>is</strong>tical point of view, it does not matter if the school assessment marks are‘too high’ or ‘too low’. The moderation process makes the required adjustment.The r<strong>an</strong>k order of the students based on the moderated assessments <strong>is</strong> the same asthe r<strong>an</strong>k order of the students based on the school assessments, even though it maynot be the same as the r<strong>an</strong>k order based on the examination marks.There are occasions when, for technical reasons, it <strong>is</strong> necessary to move thebottom moderated assessment mark above or below the bottom examinationmark.If a school submits assessment marks with two (or more) students tied on the topassessment mark, then the top moderated assessment mark <strong>is</strong> equal to the averageof the top two (or more) examination marks. A similar procedure applies if studentsare tied on the bottom assessment mark.

The <strong>High</strong>er <strong>School</strong>CertificateYour R<strong>an</strong>k <strong>is</strong> very import<strong>an</strong>t.The better you r<strong>an</strong>k within the subject the better your markwill be moderated or aligned.Assessment tasks must be done well to help you get thepossible r<strong>an</strong>k.No good just studying for your HSC exam.50% of your HSC will come from your assessment tasks.
The <strong>ATAR</strong><strong>What</strong> <strong>is</strong> <strong>an</strong> <strong>ATAR</strong>Australi<strong>an</strong> Tertiary Adm<strong>is</strong>sion R<strong>an</strong>k (<strong>ATAR</strong>) <strong>is</strong> a numerical measure of astudent's overall academic achievement in the HSC in relation to that of otherstudents.Specifically, <strong>an</strong> <strong>ATAR</strong> indicates the position of a studentrelative to their Year 7 cohort.That <strong>is</strong>, <strong>an</strong> <strong>ATAR</strong> of 80.00 indicates that students with thatUAI have performed well enough in the HSC to place them20% from the top of their Year 7 cohort, had all the Year 7students completed Year 12 <strong>an</strong>d been eligible for <strong>an</strong> <strong>ATAR</strong>.
The <strong>ATAR</strong>Eligibility for the UAIAs from the 2006 HSC, to be eligible for a UAI a student must sat<strong>is</strong>factorilycomplete at least ten units of UAI courses. These UAI courses must includeat least: Eight units from Category A courses Two units of Engl<strong>is</strong>h Three Board Developed courses of two units or greater Four subjects.In 2006 the Category B courses will be:Industrial TechnologyAccounting1Business Services ExaminationConstruction ExaminationEntertainment ExaminationHospitality Operations ExaminationInformation Technology ExaminationMetal <strong>an</strong>d Engineering ExaminationPrimary Industries ExaminationRetail Operations ExaminationTour<strong>is</strong>m Examination
The <strong>ATAR</strong>Calculating the <strong>ATAR</strong>The UAI <strong>is</strong> based on <strong>an</strong> aggregate of scaled marks in ten units of UAI coursescompr<strong>is</strong>ing:The best two units of Engl<strong>is</strong>hThe best eight units from the remaining units, which c<strong>an</strong>up to two units of Category B courses.includeThe UAI Advice Notice
The <strong>ATAR</strong>Process of calculating the UAI
The <strong>ATAR</strong>Example: Isaac Newton, Subject: Maltese Lace MakingRaw Assessment Mark<strong>School</strong> Assessment 65ModeratedAssessmentMark65 gets moderatedto 72Raw Exam Mark78 actually scored inHSCRaw HSC MarkAverage of 72 <strong>an</strong>d78 = 75
The <strong>ATAR</strong>Raw HSC marksRaw HSC marks, rather th<strong>an</strong> the Board’s reported HSC marks, are usedin the scaling process.A student’s raw HSC mark in a course <strong>is</strong> the average oftheir raw examination mark <strong>an</strong>d their raw moderatedschool assessment. These marks are not reported tostudents
The <strong>ATAR</strong>ScalingInitial st<strong>an</strong>dard<strong>is</strong>ationBefore the scaling algorithm <strong>is</strong> implemented, a linear tr<strong>an</strong>sformation <strong>is</strong>applied to the raw HSC marks in each course to set the top mark to acommon value.The marks in each course are then st<strong>an</strong>dard<strong>is</strong>ed to a me<strong>an</strong> of 25 <strong>an</strong>dst<strong>an</strong>dard deviation of 12 on a one-unit bas<strong>is</strong>.

The <strong>ATAR</strong>Calculating scaled me<strong>an</strong>s <strong>an</strong>d st<strong>an</strong>dard deviationsThe model underpinning the scaling algorithmspecifies that the scaled me<strong>an</strong> in a course <strong>is</strong>equal to the average academic achievement ofthe course c<strong>an</strong>didature, where for individualstudents, the measure of academic achievement<strong>is</strong> taken as the average mark in all coursescompleted.Report on the Scaling of the 2003-2010NSW <strong>High</strong>er <strong>School</strong> Certificate
The <strong>ATAR</strong>Example: Isaac Newton, Subject: Maltese Lace MakingScalingWhen all students of‘Maltese LaceMaking’ marks (in allsubjects) wereaveraged the me<strong>an</strong>was found to be 60Raw HSC Mark75 (lets say th<strong>is</strong> wasslightly above the averagefor th<strong>is</strong> course)Scaled mark for LaceMakingSince Isaac attained amark of 75 (slightlyabove the average) th<strong>is</strong>would be scaled to amark slightly above thescaled me<strong>an</strong> of 60, tosay 63
The import<strong>an</strong>ce of positionThe impact of st<strong>an</strong>dard deviation
The <strong>ATAR</strong>Scaled me<strong>an</strong>s & st<strong>an</strong>dard deviations for extension coursesThe scaled me<strong>an</strong>s <strong>an</strong>d st<strong>an</strong>dard deviations are determined by theperform<strong>an</strong>ce of the Extension students on the corresponding 2 unit courses.The exceptions are H<strong>is</strong>tory Extension which c<strong>an</strong> be completed by both ModernH<strong>is</strong>tory <strong>an</strong>d Ancient H<strong>is</strong>tory students, Engl<strong>is</strong>h Extension 2 <strong>an</strong>d MathematicsExtension 2.A scaled me<strong>an</strong> <strong>is</strong> determined for the Modern H<strong>is</strong>tory students in H<strong>is</strong>toryExtension on the bas<strong>is</strong> of their perform<strong>an</strong>ce in the 2 unit Modern H<strong>is</strong>tory course.A scaled me<strong>an</strong> for the Ancient H<strong>is</strong>tory students in H<strong>is</strong>tory Extension <strong>is</strong> found in asimilar m<strong>an</strong>ner. The scaled me<strong>an</strong> for H<strong>is</strong>tory Extension <strong>is</strong> then set equal to theweighted average of these two scaled me<strong>an</strong>s.

The <strong>ATAR</strong>Calculating aggregates <strong>an</strong>d percentilesAggregates of scaled marks are calculated to one decimal placePercentiles are then determined for these aggregates.A percentile, in th<strong>is</strong> context, shows the position ofa student relative to their UAI cohort.
