The Plastics and Materials Processing Industry Training Organisation (PaMPITO) has completed the review of the unit standards listed above.

 

Date new versions published                                                          September 2011

 

Planned review date                                                                           December 2016

 

Summary

 

In June 2011, PaMPITO carried out a review of these unit standards which had passed their planned review date.  Members of the review group were emailed the unit standards in order to submit feedback which was then discussed in a one day meeting.  The review group was made up of industry representatives including PaMPITO field staff and representatives from three organisations who carry out plastic extrusion processes.  The review group also included a roving assessor who has extensive practical experience in extrusion.  The purpose of the review was to ensure the unit standards are relevant, logical, fit for purpose and continue to reflect the requirements of the sector.

 

Consideration was given to technology and equipment advancements, industry best practice and requirements, changes in legislation and issues raised regarding ease of assessment.  As a result of this, two new unit standards were developed at Levels 3 and 4.  Wider consultation was carried out by email with two organisations from the extrusion sector that were not in the initial review group and suggested changes were discussed and incorporated where appropriate.  All changes to these unit standards have been endorsed by the review group.

 

Main changes

 

·      Unit standard 284 was designated category C as the two outcomes were split into two new unit standards to reflect the difference in complexity.

·      New Level 3 unit standard 27631 was created taking Outcome 1 from unit standard 284 and Outcome 3 from unit standard 282.

·      New Level 4 unit standard 27571 was created as the skills of trialling an extrusion product or process in expiring unit standard 284 were deemed to be at a higher level of complexity and warranted their own unit standard.

·      New Outcome 3 was added to unit standard 282 to include knowledge about the consequences of not applying quality procedures during the extrusion process and actions to be taken.

·      Outcomes and evidence requirements were rewritten to clarify assessment requirements, and put into a logical order.

·      Range statements were amended to improve assessment guidance.

·      A last date of assessment for superseded versions of standards was specified.  This date is 31 December 2014.

 

The category C unit standard will expire at the end of December 2014.
