Connexis has completed the review of the unit standards listed above.

Date new versions published                                                               April 2020

Planned review date                                                                              December 2025

Summary

Connexis identified a group of unit standards due or overdue for review.  Some of these have had very low usage in the last five years and are not in current Connexis programmes.  After consultation with stakeholders with consent to assess these unit standards, a group of unit standards were set to expire.  The remaining unit standards were reviewed by a group of subject matter experts in April – November 2019.

Main changes

· Guidance information was updated in all standards to ensure currency with industry knowledge and practice.

· Some standards were condensed to one outcome to more accurately reflect the task being assessed.

· Titles for unit standards 14328, 14331, 16277 and 16282 were amended to improve clarity.

· Category D standards were designated expiring without replacement, as identified in the table below, principally because of low usage.

Category D unit standards will expire at the end of December 2022

The last date for assessment of superseded versions of Category B unit standards is December 2022

All changes are in bold.

Key to review category
A	Dates changed, but no other changes are made - the new version of the standard carries the same ID and a new version number
B	Changes made, but the overall outcome remains the same - the new version of the standard carries the same ID and a new version number
C	Major changes that necessitate the registration of a replacement standard with a new ID
D	Standard will expire and not be replaced
