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

Standard

91908

Title

Analyse an area of computer science

Version

1

Number of credits

3

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 areas of computer science:

  • formal languages
  • computer vision
  • computer graphics.

Resources (case studies and/or other information) will be provided, and the questions will refer to these. Candidates may use words, numerical workings, and diagrams in their responses to show their reasoning.

For formal languages, questions may cover: regular expressions; simple finite-state automata; context-free grammars (CFGs).

For computer vision, questions may cover: noise, thresholding, edge detection, image processing for computer vision, applications.

For computer graphics, questions may cover: matrices and transformations, line and circle drawing, line and circle algorithms, graphics algorithms, image rendering, lighting.

Special notes

Teachers are encouraged to familiarise themselves particularly with Explanatory Note 4 of the Achievement Standard and to see how this has been exemplified in the 2021 assessment.

Questions will prompt the candidate to explore aspects of the area of computer science in such a way that their responses in whole or in part can be assessed against the criteria for Excellence, Merit, and Achievement (that is, the assessment will not comprise “Excellence-only”, “Merit-only”, and “Achievement-only” questions).

Teachers are encouraged to help their students to develop answering techniques to ensure that they are able to respond clearly and concisely within the total recommended word limit. Responses that exceed this may not be considered for assessment past the 1500-word limit.


Standard

91909

Title

Present a reflective analysis of developing a digital outcome

Version

1

Number of credits

3

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 8 of The New Zealand Curriculum (see the Teaching & Learning Guide for digital technologies).

The questions will require candidates to discuss the decisions made during the development of the digital outcome, and to draw conclusions about the outcome and/or the development process (see Explanatory Notes 4 and 5 of the Achievement Standard).

The discussion will require candidates to focus on how any TWO of the following “implications” were considered during the development of the digital outcome:

  • cultural issues
  • legal issues
  • ethical issues
  • issues relating to intellectual property
  • issues relating to sustainability
  • issues relating to privacy
  • issues relating to accessibility
  • issues relating to usability
  • issues relating to functionality
  • issues relating to aesthetics
  • end-user requirements
  • health and safety issues.

Candidates must 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 sample image showing a relevant digital component of the outcome in the software used, for example:
    • the HTML / CSS for a website in a text editor (e.g. VS Code, Notepad++)
    • the “layers” view of a vector or raster graphic (in e.g. Inkscape / Illustrator, GIMP / Photoshop)
    • the source code for controlling an electronic device (in e.g. Arduino C, PBasic)
    • the CAD / CAM file for a 3D model (in e.g. Blender, Fusion 360, SketchUp)
    • the source code for an application in a suitable text editor (e.g. VS Code, Replit).

Candidates may access their digital outcome for reference only (they may not copy / paste information into the assessment response).

Special notes

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

Teachers are encouraged to help their students to develop answering techniques to ensure they are able to respond clearly and concisely within the total recommended word limit. Responses that exceed this may not be considered for assessment past the 1500-word limit.
