Competenz has completed the review of the unit standards listed above that were registered in October 1994 and June 1995.

 

Date new versions published                        July 2004

 

New comments by date                        July 2008

 

Expiry date of new versions of the unit standards                        December 2009

 

Summary of review and consultation process

 

Two northern and southern pilot meetings involving Competenz, industry representatives, and accredited providers were convened September 2002 to initially deliberate the concept of Maintenance and Diagnostics as it applies to Mechanical Engineering.  Group discussion centred on the mix of unit standards available to candidates in the current level 4 and level 5 qualifications, in addition to future qualification options that may be applicable to this technologically dynamic industry.

 

The groups were also advised that a significant number of unit standards available to candidates in the level 4 and level 5 qualifications showed an anticipated expiry date of December 2002.  These unit standards were organised into logical sets and assigned to representatives on the basis of expertise and interest.  Consequently, six expert sub-groups emerged from the initial pilot groups to manage the full review on a progressive basis.  The full review is scheduled for completion October 2003, however, the extent and complexity of the review programme has now seen the completion date taken to mid 2004.

 

This review report summarises the outcomes of the third expert sub-group.

 

It was also recognised that some of these unit standards apply to other Competenz sectors and qualifications, including Metal Casting, Composites, Machining and Toolmaking, Heating, Ventilating and Air Conditioning, Refrigeration, and Fabrication.  On this basis, representatives from these sectors were invited to provide input as applicable.

 

Main changes resulting from the review

 

Part A: Engineering Drawing and Design

·        Unit standards 2430 and 2431: improved special notes.

·        Unit standard 2432: title changed and improved special notes.

·        Unit standard 2433: improved special notes, and the introduction of unit standard 2780 as a recommended unit standard for entry to programmes that include assessment against 2433.  The recommended standard was included to emphasise the necessity for a rudimentary knowledge of pc operations prior to undertaking assessment.  Title changed.

·        Unit standard 2434: improved special notes.  The requirement for progressive tolerance calculations removed from element 2.  Title changed.

·        Unit standard 2435: designated as expiring due to low usage.  Replaced by new unit standard 20802.  Special note 2 stresses that this unit standard is intended for users of 2D software applications only.  Credit level reduced to reflect the user-friendly nature of contemporary CAD software packages.

·        Unit standard 2436: improved special notes.  Performance criteria range statements added/updated.  Credit level reduced as per the rationale given in 20804 above.  Title changed.

·        Unit standards 2437, 2438, and 2439: designated as expiring due to low usage.  Three unit standards merged to form one advanced manual drawing unit standard (20803), and one advanced CAD drawing unit standard (20804).  Each unit standard is applicable to a range of sectors, as defined in special notes.

·        Unit standard 2440 designated as expiring and not replaced.

·        Unit standard 2441: improved special notes.  Amended title reflects the requirement for at least two 3D models.  Credit value unchanged for reasons as alluded to above.

 

Part B: Engineering - Materials

·        Unit standard 4795: level changed from 1 to 2.  New version broadens the range of engineering materials across all elements.  Previous concentration on engineering metals now carried to unit standard 4796.  Replaced with new unit standard 20917.

·        Unit standard 4796: re-written to serve as a complementary unit standard to 4795, but with a concentration on engineering metals.  More advanced elements of metal tests and heat treatments carried to later unit standards.  Replaced with new unit standard 20799.

·        Unit standard 4797: expanded to better address the differences between ferrous and non-ferrous metals.  Credit increased to 5.

·        Unit standard 4798: designated as expiring, as content covered in reviewed unit standards described above.

·        Unit standard 4799: updated and expanded special notes.  Previous element 3 not entirely relevant to the overall performance outcome: replaced by new element calling for interpretation of test results.

·        Unit standard 4800 and 4801: addition of definitions under special notes.  Assessment expectations clarified through the re-phrasing of performance criteria and addition/expansion of range items.  Credit values amended in each instance.  Titles changed.

·        Unit standard 4802: performance outcome made more achievable through the reduction in assessment requirements, as outlined in updated special notes.  Credit value reduced from 40 to 10.

·        Unit standard 4803: replaced by new unit standards 20800 and 20801.

 

Unit standards categorised as category C or D expire at the end of December 2006.
