The Plumbing, Gasfitting and Drainlaying
Industry Training Organisation Ltd has completed the review of the unit
standards listed above.
Date new versions published
October 2007
Planned review date
December 2012
Summary of review and consultation
process
The unit
standards listed above were due for review. The review took place in the context of
the review of the plumbing, gasfitting, and drainlaying national
certificates. Apart from unit
standards 2131 and 2158, the review did not include Level 5 unit
standards.
Changes to these unit standards were based on comments received from industry and from training providers as a result of an extensive consultation and feedback process that took place over a four and half year period. Plumbing, Gasfitting and Drainlaying Industry Training Organisation Ltd advisory groups, and review teams for each of the plumbing, gasfitting, and drainlaying sectors comprising industry and training provider representatives considered the comments. The Plumbers, Gasfitters and Drainlayers Registration Board also participated in, and contributed to, the review process.
The focus of the review was on updating content to reflect current practice; quality improvement; and confirmation that the classification, Level, and credit values were consistent with the content and purpose of each unit standard. The review teams took into consideration changes to legislation and changes in technology applicable to the unit standards before recommending and endorsing the changes. An additional element was added to many of the unit standards for evidence of the candidate's knowledge, in terms of the unit standard outcomes, of the applicable regulatory requirements, the methods and materials selected, and, in many cases, the application of relevant underpinning concepts and principles.
New unit
standards were developed as a result of the review to reflect identified skill
gaps, and are listed in the 'Review Categories and changes to classification,
title, Level, and credits' section of this report.
Main changes resulting from the review
· Unit standard 2139 was reclassified from Core Construction domain to Core Plumbing, Gasfitting, and Drainlaying domain.
· Unit standards 1099 and 1122 were reclassified from Drainlaying domain to Core Plumbing, Gasfitting, and Drainlaying domain.
· Unit standard 2157 was reclassified from Plumbing domain to Core Plumbing, Gasfitting, and Drainlaying domain.
· Category C reviews - Unit standards 1110 and 1111 were replaced by unit standard 23846; unit standards 2131 and 2158 were replaced by unit standard 21887; unit standards 2135 and 2162 were replaced by unit standard 21845; unit standards 2145, 2160, and 2161 were replaced by unit standard 23841; unit standards 2147, 2163, 2164, and 2165 were replaced by unit standard 21884; unit standard 2151 was replaced by unit standards 23850 and 23851; unit standards 2154 and 2155 were replaced by unit standard 21885; and unit standard 2156 was replaced by unit standard 21886.
· Category D reviews - Unit standards 2118, 2121-2124, 2129, 2133, 2140, and 2141 will expire and will not be replaced.
· Unit standards 1107, 1115, 1120, 1121, 2114, 2115, 2136-2138, and 2159 have been modified to allow demonstration of knowledge rather then practical performance.
· Unit standards 1099, 1101, 1104, 1106-1109, 1112, 1114, 1115, 1117, 1118, 1120, 1121, 1122, 2114-2117, 2132, 2136-2139, 2143, 2144, 2149, 2153, 2157, and 2159 had changes of title to reflect their outcomes, as reviewed.
· Unit standards 1100, 1107, 1112, 1114, 1115, and 1118 had increases in Level.
· Unit standards 1120, 1121, 2114, 2115, 2136-2139, 2143, and 2159 had decreases in Level.
· Unit standards 1099, 1104, 1107, 1112, 1117, 1122, 2116, and 2144 had increases in credits.
· Unit standards 1100, 1106, 1115-1116, 1118, 1121, 2114, 2115, 2132, 2136-2138, 2153, 2157, and 2159 had decreases in credits.
· Entry information has been updated, where applicable, to include the prerequisite 'Current plumbing certificate or licence as issued under the Plumbers, Gasfitters, and Drainlayers Act 2006'.
· Special notes have been reworked to include: more extensive lists of relevant legislation, codes, standards, and guides; reference, where applicable, to the Plumbers, Gasfitters, and Drainlayers Regulations 1977; applicable definitions; applicable ranges; and other notes deemed necessary.
· Elements and performance criteria have been reworked, extensively in most cases, to: incorporate user feedback; to improve clarity and specificity; to reflect current good practice; to remedy some errors; and to allow, with an element in unit standard 1109, demonstration of knowledge rather than practical performance.
· Most of the unit standards have had an element added regarding the demonstration of knowledge of regulatory requirements, selection of methods and materials, and, where applicable, underpinning concepts and principles, as applied to the outcome or outcomes covered by the unit standard.
