Assessment task
A formally submitted piece of assessment completed during the HSC year (as opposed to the external HSC examination). HSC assessment tasks contribute 50% of a student's final mark (combined with the external exam mark, which also contributes 50%). Each assessment task must be submitted to NESA before the task is given to students. Tasks must assess specified course outcomes and comply with NESA's assessment certification requirements.
Achievement standard
A description of the quality of learning expected at a particular level of achievement in a course. In NSW HSC contexts, achievement standards inform Band descriptors and are used in moderation of school-based assessment tasks. The Standards Materials published by NESA include annotated student work samples at each Band to illustrate achievement standards.
Band 6
The highest performance band in an HSC course. A Band 6 student in HSC Mathematics Advanced, for example, demonstrates extensive knowledge and understanding of the course content, applies mathematical reasoning in complex and unfamiliar contexts, and communicates mathematical ideas with precision. Band 6 questions typically involve synthesis across multiple outcomes, extended reasoning, or novel problem setup.
Band descriptor
NESA's published description of the knowledge, skills, and understanding expected at each performance band in a course. Accessible via NESA's website for each HSC Mathematics course. Band descriptors are useful when calibrating question difficulty — if you're writing a Band 5–6 question, the descriptor tells you what performance level it should require.
Course specifications
NESA's published document for each HSC course specifying the course structure, outcomes, content, sample questions, and assessment requirements. The 2024 course specifications for each HSC Mathematics course are the authoritative documents for curriculum planning. Outcome codes referenced in curriq are drawn from these specifications.
Criterion-referenced marking
A marking approach in which student work is assessed against a defined set of criteria, rather than ranked against other students (norm-referenced marking). HSC marking is criterion-referenced: each question has published marking criteria, and marks are awarded based on whether the student's response meets those criteria, regardless of how other students performed.
HSC Band
The six performance bands used by NESA to report HSC results. Band 1 is the lowest, Band 6 is the highest. Each band has a descriptor that specifies what a student performing at that level is expected to know and be able to do. Band 5–6 items on the HSC paper typically require multi-step reasoning, unfamiliar contexts, or proof — not just procedure application.
Marking guidelines
NESA's published marking criteria for the HSC external examination, released after each exam. They specify what constitutes a full mark, partial marks, and common acceptable alternative methods for each question. HSC maths teachers use these as a calibration tool when writing their own school-based marking criteria.
Moderation
The process of ensuring consistency in assessment marking across teachers and schools. In NSW, school-based assessment marks are moderated by NESA using the external HSC examination to ensure that a school's internal marking standards are consistent with the state standard. Teachers writing assessment tasks and marking criteria should apply criterion-referenced marking aligned to NESA's marking guidelines.
NESA outcome code
A alphanumeric label identifying a specific learning outcome in an HSC Mathematics syllabus. The prefix identifies the course and strand (e.g. 'C' = Calculus in Advanced; 'ME-P' = Proof in Extension 1; 'MEX-N' = Complex Numbers in Extension 2); the number identifies the outcome within that strand. Example: C1.2 = HSC Mathematics Advanced, Calculus strand, outcome 1.2 (Differential Calculus). Every question in an HSC exam is keyed to one or more outcome codes, and marking criteria are written in those terms.
NESA reference sheet
The official formula sheet provided to students during HSC Mathematics examinations. There are two versions: one for HSC Mathematics Standard 1 & 2, and one for HSC Mathematics Advanced, Extension 1, and Extension 2. The reference sheet includes formulas for financial maths, measurement, trigonometry, calculus, and statistics. Students must be familiar with what is and is not on the sheet — an error or omission in the reference sheet is not an acceptable excuse in HSC marking.
NESA-approved calculator
A calculator that meets NESA's criteria for use in HSC examinations. NESA publishes an approved calculator list; students may only use calculators on this list in the HSC. Scientific calculators are permitted in all four HSC Mathematics courses; CAS (Computer Algebra System) calculators are not permitted. The NESA-approved calculator list is updated periodically.
Outcome coverage
A record of which syllabus outcomes have been addressed in teaching and/or formally assessed across a school year. Outcome-level tracking — distinct from topic-level tracking — tells you not just that 'calculus has been taught' but whether C1.2 (Differential Calculus) and C1.3 (Applications of Differentiation) have each been specifically assessed. A gap in outcome coverage can be exposed on the HSC paper even when the topic appears to have been covered.
RAP data
Results Analysis Package. Data published by NESA after each HSC examination, showing how students in each school performed on each question relative to the state. RAP data shows state mean, school mean, and question-level detail. It is available through NESA's Schools Online portal and is used for school-level reporting and curriculum planning.
Syllabus outcome
A specific, assessable learning outcome in a NESA syllabus. Each outcome has a code, a description, and associated content dot points. In HSC Mathematics, outcomes define what students should know and be able to do in each strand. Assessment tasks and exam papers are designed to sample a range of outcomes, and marking criteria are written in terms of outcomes.
Working mark
A mark awarded for correct working-out steps, independent of whether the final answer is correct. In multi-step HSC questions (typically 2 marks or more), markers award marks per step. A student who makes an arithmetic error at the end but has correct conceptual working can receive all but the final mark. This is why evaluating working — not just answers — matters in HSC marking.
