91620: Implement complex procedures to integrate parts using resistant materials to make a specified product

Updated December 2019. This document has been updated in its entirety due to changes that have been made in the standard to address issues seen in moderation. This clarification applies to all versions of the standard.

General notes

This standard requires students to implement complex procedures using resistant materials (see EN4) to precisely integrate two or more assembled parts in a specified product (see EN3).

Specifications (see EN5), need to be agreed prior to the product being made. Specifications can be teacher-given or developed in negotiation with the student, and should be evident in the student documentation. Specifications must be of sufficient rigour to enable the student to meet the standard.

Complex procedures

These complex procedures require students to trial techniques and use findings to inform the selection of techniques and tests, in order to make a specified product that incorporates two or more assembled parts (see EN3).

Students should schedule (see EN8) the order of techniques and tests for the parts that require precise preparation and integration. For example, a step-by-step construction plan to show the sequence of techniques and tests for parts that require precise integration in cabinet making.

Preparation for integration

The integration environment requires student consideration to ensure that the workspace is ready for use. This may include preparation of the workspace, e.g. sourcing and preparation of tools, equipment and assembly aids (see EN6). Student evidence of the preparation could be written, or shown via annotated photos or video. Assessor verification is required.


To reduce the chance of error during integration, students should identify the stages in the construction sequence where decisions need to be made. Tests to ascertain the precise alignment of parts, such as the fit or checking for square or level should be reviewed at reference points. Examples of reference points may include centre lines or a squared end (see EN7).

Student evidence of the testing and findings could be written, or shown via annotated photos or video. Assessor verification is required.

Health and Safety

Students need to be aware of and document their compliance with health and safety regulations throughout the preparation, integration and testing procedures. Student evidence of compliance could be written, or shown via annotated photos or video.

Assessor verification should clearly indicate how the students have complied with health and safety regulations.

Merit and Excellence

Assessor verification is required for Merit and Excellence. Evidence needs to be provided for the manner in which techniques are implemented, whether the specified product met the specifications, and the quality of the finished product.

For example, the assessment schedule and/or assessor verification/attestation should clearly indicate how each student has executed complex procedures independently and accurately (Merit), and economised time, effort and materials (Excellence). These annotations could be derived from classroom observation and/or discussions with students.
