Every HSC mathematics teacher receives RAP data after the external exam. The teachers who use it systematically produce above-state-average results because they know exactly which outcomes to prioritize.
This guide explains how to read the NESA data available to you, what to look for, and how to build a teaching program around it.
What NESA Data is Available?
NESA publishes several data sources relevant to HSC maths program planning. Understanding what each one contains is essential.
RAP data (Results Analysis Package): Published after each HSC exam and available through Schools Online. It contains your school's mean score on each specific HSC question alongside the state mean, revealing how your students performed relative to the state.
HSC marking guidelines: Published after each exam on the NESA website. This document contains the exact marking criteria for every question, explicit notes on acceptable alternative methods, and common errors.
Standards Materials: Published by NESA for each course, containing annotated samples of student work at each performance band. They demonstrate exactly what Band 4, Band 5, and Band 6 work looks like on specific question types.
Course specifications and syllabus: The canonical document for each course. Every question on the HSC paper is drawn directly from the content and outcomes described in this document.
How to Read RAP Data Effectively
The standard approach of looking for questions where students performed poorly misses the structural insight. The required approach is identifying which outcomes had the largest gap between your students and the state.
A question with a state mean of 2.3/3 and your school mean of 2.1/3 is a baseline question. A question with a state mean of 1.4/3 and your school mean of 0.8/3 represents a genuine outcome-level weakness relative to peers.
Map each RAP question to its outcome code using NESA's marking guidelines. This creates a clear gap map detailing which exact outcomes your class underperformed on relative to the state. This forms your Year 12 priority list.
How to Map RAP Gaps to Your Teaching Program
With a gap map organized by outcome code, make deliberate decisions regarding:
Outcomes requiring more teaching time. If C1.3 (Applications of Differentiation) shows a persistent gap across multiple cohorts, it is a teaching emphasis problem. It demands more time in your program and more structured practice.
Outcomes requiring more formal assessment. Outcomes taught but not repeatedly assessed in school-based tasks lead to underperformance on the HSC paper. Drill practice is not a substitute for formal assessment.
Outcomes requiring exam-condition practice. Gaps on questions students handle well in class but fail in exams require a different intervention. These students need timed practice, past-paper exposure, and exam strategy work. (Note: Ensure exam conditions strictly mirror the physical layout and timing of the actual HSC).
How to Calibrate Questions Using Marking Guidelines
NESA's marking guidelines provide a public rubric for HSC quality. Before writing an assessment task question, review how NESA assessed the identical outcome code in recent exams.
Identify the following:
- What precise level of detail does NESA's mark scheme require for each step?
- Which specific alternative methods does NESA accept?
- Which mathematical errors does NESA consider sufficient to withhold a mark?
Schools that calibrate internal questions and rubrics against NESA's marking guidelines produce students who excel on the external exam. Schools with misaligned rubrics produce students who are overconfident about their marks.
How to Calibrate Expectations Using Standards Materials
NESA's Standards Materials show annotated student work at each band, revealing the exact quality of a Band 4 or Band 6 response.
Use Standards Materials to calibrate your assessment tasks. Take a question you wrote and ask: would the Band 4 sample in the Standards Materials receive a good mark on your rubric? Would the Band 6 sample receive full marks? If not, your question or rubric is misaligned with NESA's expectations and must be rewritten.
How to Build Outcome Tracking into Your Program
Mapping classroom activities to outcome codes manually and maintaining a spreadsheet of taught and assessed outcomes is time-consuming but necessary. A program built on outcome-level data produces better results than one built on a standard topic sequence. Teachers who know which outcomes their cohort has been formally assessed on make better decisions about assessment frequency and content emphasis.
curriq tracks outcome coverage across every assessment task you run, and reports marking results at the outcome level rather than the question level.

FAQ
Where do I access my school's RAP data?
You access your school's RAP data through the NESA Schools Online portal using your school login credentials after the HSC results are released.
How often should I review NESA marking guidelines?
You should review the NESA marking guidelines every time you write a new school-based assessment task to ensure your internal marking criteria align with external expectations.
What is the difference between marking guidelines and Standards Materials?
Marking guidelines provide the criteria and acceptable methods for awarding marks on a specific question, while Standards Materials provide actual annotated student responses demonstrating the overall quality of work expected for each performance band.
