Connexis has completed the review of the unit standards listed above.
Date new versions published July 2020
Planned review date December 2025
Summary
These unit standards were reviewed as part of the development of the New Zealand Certificate in On-site Wastewater Management System Design (Level 4) [Ref: 4126], which occurred from August 2019 to March 2020. Consultation occurred in January and March 2020 with stakeholders holding consent to assess against these unit standards.
Main changes
· Guidance information was updated in all standards to ensure currency with industry knowledge and practice.
· Titles for some unit standards were altered, as identified in the table below, to reflect changes in practice in the wastewater treatment industry.
· Levels for some unit standards were lowered, as identified in the table below, to better align with the job role.
· Credit values for some unit standards were changed, as identified in the table below, to more accurately reflect the learning hours required for these tasks.
· Unit standard 25126 was designated expiring without replacement as it is no longer required.
· Unit standard 25127 and 25128 had major changes that necessitated the registration of replacement standards.
· Two new unit standards were developed to meet the requirements for risk management and quality assurance.
Category C and D unit standards will expire at the end of December 2022
