Waihanga Ara Rau Construction and Infrastructure Workforce Development Council has completed the review of the unit standards listed above.
Date new versions published May 2024
Planned review date December 2029
Summary
Waihanga Ara Rau Construction and Infrastructure Workforce Development Council initiated a review of unit standards in the Plumbing domain which was triggered by the regular 5-year review cycle.
The unit standards in this application have been reviewed to update them in line with current industry practice, and to ensure they are fit for purpose.
A series of Technical Advisory Group (TAG) meetings were held between November 2022 and November 2023 to complete this review. The Technical Advisory Group consisted of industry and provider representatives with consent to assess, and representatives from industry stakeholder organisations including the Plumbing, Gasfitting, and Drainlaying Board and the Ministry of Business, Innovation and Employment.
Following the review, public consultation was held in November and December 2023. Feedback received was reviewed and decisions were made in consultation with the TAG group representatives resulting in the changes below.
Main changes
· Guidance information, legislation, performance criteria and range statements were amended across the suite of unit standards to reflect the content and scope of the work, and in line with current industry practice.
· Minor wording changes were made across the suite for clarity and to meet current industry terms.
· Unit standard 23848 was designated to expire without replacement as this is no longer required by industry.
· Unit standards 30543, 30544, 30551, 30552, 30554, 30608 and 30615 were designated to expire and will not be replaced. This is due to maintenance not being completed at the time of installation and this was a barrier to completion.
· Nine new unit standards (33332 –33340) have been developed with separate installation and maintenance outcomes.
· Unit standard 23847 was moved up to level 4 to reflect the complexity of the outcomes required.
· Unit standard 30527 had a title change and credits were reduced to 3 to accurately reflect the notional hours required for learning and assessment completion.
· Unit standards 30545, 30598, 30599, 30605, 30606, 30609 and 30614 had titles amended to more accurately reflect the outcomes, and align with current industry terms.
· Unit standard 30555 was moved down to level 3 to more accurately reflect the level of performance required.
· Unit standard 30604 had the credit value increased to 6 credits to more accurately reflect the notional hours required for learning and assessment completion.
· Unit standard 30609 had an additional outcome added to cover on-site drinking water treatment in accordance with The Drinking Water Acceptable Solutions (Taumata Arowai).
· Unit standard 30611 had the credit value increased to 5 credits to more accurately reflect the notional hours required for learning and assessment completion.
Category D unit standards will expire at the end of December 2028.
