Question 1

What is NCEA AS 91352 about?

Accepted Answer

This standard asks you to show you understand how materials are processed in industry — things like mixing, heating, filtering, or testing products. You need to describe what happens at each step, explain why certain tests matter, and compare how processing works differently in a school lab versus a real factory, including the different safety rules.

Question 2

What do students need to do for AS 91352?

Accepted Answer

1. Describe processing operations (like mixing, heating, filtering, or separating) and explain how they affect the final product 2. Identify and describe the tests used during processing and explain why they matter for quality control 3. Create or explain a processing sequence that shows operations and tests in the correct order 4. Compare processing methods in the classroom with industrial processing, and explain the practical and safety differences 5. Discuss health and safety regulations and explain why they differ between school and industry settings

Question 3

What's the difference between Achieved, Merit, and Excellence for AS 91352?

Accepted Answer

Achieved: You describe what each processing operation does and what tests are used, show them in sequence, and mention some differences between school and industrial processing. Merit: You explain *why* specific processing operations work the way they do and *why* particular tests are chosen, and clearly describe the practical and safety differences between classroom and industrial contexts. Excellence: You compare and contrast different processing methods and tests, discuss which ones suit different materials or purposes, and explore how testing results actually change processing decisions in real situations.

Question 4

What mistakes do students typically make in AS 91352?

Accepted Answer

1. Not explaining the *reason* operations or tests are used — just listing what happens without the 'why' 2. Failing to compare classroom and industrial processing adequately, or missing the safety regulation differences altogether 3. Not discussing how test results actually influence what happens next in the process
