5. Validation
Validation is a quality review process. It involves
checking that the assessment tool produced
valid, reliable, sufficient, current and authentic
evidence to enable reasonable judgements to be
made as to whether the requirements of the
relevant aspects of the Training Package or
accredited course had been met. It includes
reviewing and making recommendations for
future improvements to the assessment
tool, process and/or outcomes.

7. Moderation
Moderation is the process of bringing
assessment judgements and standards into
alignment. It is a process that ensures the same
standards are applied to all assessment results
within the same Unit(s) of Competency. It is an
active process in the sense that adjustments to
assessor judgements are made to overcome
differences in the difficulty of the tool and/or the
severity of judgements.

settings
Identified barriers:
Structural (i.e., the organizational and resource
aspects) – financial, variations of definitions across
key documents
Process (i.e., the practices and activities that take
place) – rolling enrolments, partnering
arrangements, workloads
Personal factors (i.e., the attitudinal, assessment
literacy and expectations of the key players).

Moderation is desirable but not mandatory and is described in the NQC documents as a quality control process. Within a moderation process, adjustments to student results should be made prior to their finalisation of the results if the judgements of the assessor have been determined to be too harsh or lenient. Similarly, moderation can lead to adjustments to student results if the assessment tools have been determined to be too easy and/or difficult. Adjustments are made therefore to the students’ results prior to finalisation. This process helps to bring standards across RTOs into alignment and therefore ensure fairness and comparability of standards across the sector. Although moderation is desirable within the VET Sector, particularly in high risk assessments, it is not necessary under the AQTF as in many instances the benefits may not outweigh the costs.
Here is also some examples of the outcomes of a moderation process. Like validation, it could lead to recommendations for improvements to the tool, but unlike validation, it may require altering students’ results prior to finalisation to bring standards into alignment. There may also be a requirement for some form of accountability.
This table provides a good summary as to the difference between validation and moderation. It can be found in the NQC Implementation guide.
Although yet to be pursued at the national level within the VET Sector, statistical moderation could be used to ensure that RTO based assessments are comparable throughout the nation, particularly if grades or marks are to be reported. However, to implement this moderation process, some form of a common assessment task(s) would need to be introduced at a national level in the VET sector (e.g., external exam or standardised assessment tools) to moderate the organisation-based assessments. If a common assessment task was used to statistically moderate organisation-based assessments, the statistical moderation process would maintain the rank order of the candidates’ scores (as determined by the assessor/organisation) but it would bring the distributions of scores across groups of candidates (from other organisations or assessors) within the same units within a qualification into alignment. That is, statistical moderation adjusts the organisation-based assessments in accordance with candidates’ performances on common external tasks. It should be acknowledged that any adjustment to a candidate’s scores is determined by the external scores for the whole organisation’s cohort, not by the candidate’s own external score. It is also important to note that statistical moderation does not change the rank order of candidates, as determined by the organisation’s scores. A candidate given the top score for an assessment task by his/her organisation would have the top score after statistical moderation, no matter how they performed on the external task. The process recognises that organisations are in the best position to make comparative judgements about the performance of their candidates and these comparative judgements are not changed as a result of the statistical moderation. Statistical moderation entails adjusting the level and spread of each organisation’s assessments of its candidates in a particular qualification, to match the level and spread of the same candidates’ scores on a common external task. If a common assessment task was to be completed by all candidates across the nation or within an industry area, it could become the common standard against which organisation’s assessments could be compared. At a national level, the organisation-based assessments could be statistically moderated using:A common exam across all qualifications based on measuring generic/employability skills.Qualification specific national exams (similar to those used for licensing purposes).National common assessment tools within each qualification that would need to be judged centrally. The major benefit of statistical moderation is that it provides the strongest form of quality control over organisation-based assessments. It can also be less expensive to implement and maintain (if paper-based) than external moderation processes. It would however require the introduction of some form of common assessment task(s) at the national level. If the common assessment task was paper-based (as has been typically implemented in other educational sectors due to reduced costs associated with the implementation and scoring procedures), then any adjustments to candidate results would be limited to estimates of candidates’ cognitive skills (i.e., knowledge and understanding); and therefore may have limited face and content validity within the VET sector.
External Approaches (Validation and Moderation)There are various external approaches to assessment validation and moderation. One approach would be for an external person (or a panel of people) to visit the organisation to judge the way in which candidates’ evidence were collected and judged against the Unit(s) of Competency. Differences between the local and external assessment judgements could then be either:Discussed and reconciled accordingly (i.e., if conducted for moderation purposes); and/or Discussed to identify ways in which improvements to future assessment practices could be undertaken (i.e., if conducted for validation purposes). An alternative external approach would be for samples of assessment tools and/or judged candidate evidence to be sent to a central location for specialist assessors to review directly against the Unit(s) of Competency. The specialist external assessors could be representatives of the relevant national Industry Skills Council (ISC) and/or the relevant state/territory registering bodies. Again, differences between the organisation and the external-based assessments could then be discussed (e.g., for validation) and/or reconciled (e.g., for moderation) at a distance. There are a number of benefits from using external moderators/validators. These include the potential to:Offer authoritative interpretations of the standards specified within Units of Competency;Improve consistency of the standards across locations by identifying local bias and/or misconceptions (if any);Offer advice to organisations and assessors on assessment approaches and procedures; andObserve actual assessment processes in real time as opposed to simply reviewing assessment products (if site visits are included). In relation to moderation, although external approaches have greater quality control over the assessment processes and outcomes than consensus meetings, they have less quality control than statistical approaches.
Typically consensus meetings involve assessors reviewing their own and their colleagues’ assessment tools and outcomes as part of a group. It can occur within and/or across organisations. It is typically based on agreement within a group on the appropriateness of the assessment tools and assessor judgements for a particular unit(s) of competency. A major strength of consensus meetings is that assessors are directly involved in all aspects of assessment and gain professionally by learning not only how and what to assess, but what standards to expect from their candidates. It also enables assessors to develop strong networks and promotes collegiality. Another benefit from consensus meetings is that it provides opportunity for sharing materials/resources among assessors. If used for moderation purposes, consensus meetings however provide less quality control than external and statistical approaches as again, they can be influenced by local values and expectations.
Questions are often asked about how can validation processes be systematic. The Assessor Guide provides some guidance here as to what a plan for validation may include. Implementation of the plan goes towards the notion of ‘systematic’.
The Assessor Guide provides some advice as to what validation model could be suitable to different RTOs or contexts.
An project related to the initial validation and moderation papers, was one undertaken by Shelley, Chloe and Andrea regarding how validation was implemented in diverse settings. The findings indicated that in general the RTOs were struggling with implementing a systematic process and the identified barriers were….However, the RTOs were deploying a range of strategies. Refer to Handout. Discuss this with the group.
Finally, the NQC Code of Practice has included this table – and it is worthwhile talking with your group what strategies your RTO use. Get comments back. Pull all comments together and close.
