Information relating to both achievement standards

A common assessment task (CAT) is developed and marked by NZQA, and administered by a school in a single session during a period of assessment specified by NZQA.

Conditions of assessment

Candidates must complete their assessment individually under teacher supervision, in accordance with the NCEA Assessment and Examination Rules and Procedures.

The material submitted for assessment must be the candidates’ own work. Unless specified below, candidates are not permitted to access any resources (either in hard copy or online) other than those supplied in the assessment itself.

Further information

NZQA will notify schools during Term 1 of the period of assessment, and then schools must inform NZQA of the day during this period of assessment on which the CAT will be administered.

Administration and submission instructions and authenticity requirements will be published on the Digital Technologies subject page at the end of Term 2. 

Specific information for individual achievement standards




Demonstrate understanding of a computer science concept



Number of credits


Candidates will be required to respond in short and / or extended answers (800–1500 words in total) to questions relating to their choice of ONE of the following computer science concepts:

  • computer security
  • encryption 
  • error control.

There will be a question on “impacts” in relation to future-proofing or human factors.

For computer security, questions may cover: updates; firewalls; viruses and malware; a New Zealand-based* organisation’s policies or practices.

For encryption, questions may cover: techniques; passwords; attacks; a New Zealand-based* organisation’s policies or practices.

For error control, questions may cover: redundancy; automatic repeat request (ARQ); error detection schemes (e.g. error correction / notification, checksums); bar codes, credit cards, and QR codes; a New Zealand-based* organisation’s policies or practices.

* A New Zealand-based organisation or entity, for example, Countdown, "my school", or the Auckland DHB. Broad responses such as "supermarkets" or "banks" are not acceptable.




Present a summary of developing a digital outcome



Number of credits


Candidates will be required to respond in short and / or extended answers (800–1500 words in total) to questions relating to a digital outcome they have developed within the past 12 months. This digital outcome must be based on Level 7 of The New Zealand Curriculum (see the Teaching & Learning Guide for digital technologies).

Candidates will choose to answer questions about TWO of the following decisions made during development of the digital outcome:

  • sequencing of key tasks in the project
  • selection of methods to address end-user considerations
  • selection of resources used, and reasons for their use.

There will be questions on :

  • aesthetics
  • usability
  • functionality.

Candidates may prepare up to THREE images in advance to include in the assessment:

  • a single image of the digital outcome (e.g. a website; a poster; an electronic device)
  • a single image of the planning process (e.g. agile development; a planning chart)
  • a single image of the digital components of the outcome (e.g. the HTML / CSS for a website; the “layers” view of a poster; the code for an electronic device).

Candidates may also access their digital outcome in order to copy information from it and paste this into the assessment response.

Special note

The school may be required to provide a link to evidence of the candidate’s digital outcome (e.g. working files).
