The classification definitions are based on the skill level and specialisation usually necessary to perform the tasks of the specific occupation, or of most occupations in the group. The definitions and skill level statements apply to the occupation and not persons working in the occupation. The allocation of a particular occupation to a particular skill level should be seen as indicative only and should not be used prescriptively. The definitional material describing each occupation is intended primarily as an aid to interpreting occupation statistics classified to ANZSCO.

To do this, ANZSCO identifies a set of occupations covering all jobs in the Australian and New Zealand labour markets, defines these occupations according to their attributes and groups them on the basis of their similarity into successively broader categories for statistical and other types of analysis. In ANZSCO, occupations are organised into progressively larger groups on the basis of their similarities in terms of both skill level and skill specialisation.
The conceptual model adopted for ANZSCO uses a combination of skill level and skill specialisation as criteria to design major groups which are meaningful and useful for most purposes. The eight major groups are formed by grouping together sub-major groups using aspects of both skill level and skill specialisation. In designing the major groups, intuitive appeal and usefulness in both statistical and administrative applications were also important considerations.
The skill level criterion is applied as rigorously as possible at the second level of the classification, the sub-major group level, together with a finer application of skill specialisation than that applied at the major group level. Each sub-major group is made up of a number of minor groups. Minor groups are distinguished from each other mainly on the basis of a finer application of skill specialisation than that applied at the sub-major group level.
Within minor groups, unit groups are distinguished from each other on the basis of skill specialisation and, where necessary, skill level. Virtually all unit groups are at one skill level. There are only ten unit groups which contain occupations at more than one skill level.
In all but two of these unit groups, the vast majority of jobs classified to the unit group are at one skill level only. Data stored at unit group level can therefore be aggregated by skill level with a high degree of validity. Within unit groups, the distinction between occupations amounts to differences between tasks performed in occupations. All occupations are at one skill level. As a result, data classified at the major group level will provide only a broad indication of skill level.
Data at the sub-major group level will provide a satisfactory indication of skill level for many analytical purposes. Data classified at the unit group level will provide an accurate indication of skill level. Unit groups can, therefore, be aggregated by skill level to provide an indicative measure of occupations classified by skill level.
MINOR GROUP Minor groups are: subdivisions of the sub-major groups distinguished from other minor groups in the same sub-major group mainly on the basis of a less broad application of skill specialisation. UNIT GROUP Unit groups are: subdivisions of the minor groups distinguished from other unit groups in the same minor group on the basis of a finer application of skill specialisation and, where necessary, skill level. These concepts are defined in the following sections.
Individual persons are classified by occupation through their relationship to a past, present or future job.
Any particular job will typically involve an individual working for a particular employer and undertaking a particular set of tasks. People working for themselves are considered as having a job and belonging to the labour force. The similarity of tasks is defined in ANZSCO as a function of the level and specialisation of skill required to perform those tasks.
Skill is defined as the ability to competently perform the tasks associated with an occupation. The concept of skill level In ANZSCO, skill level is defined as a function of the range and complexity of the set of tasks performed in a particular occupation. The greater the range and complexity of the set of tasks, the greater the skill level of an occupation. Skill level is measured operationally by: the level or amount of formal education and training the amount of previous experience in a related occupation, and the amount of on-the-job training required to competently perform the set of tasks required for that occupation.
In general, the greater the range and complexity of the set of tasks involved, the greater the amount of formal education and training, previous experience and on-the-job training required to competently perform the set of tasks for that occupation.
Formal education and training refers to the level and amount of education and training required for competent performance of the tasks required in an occupation. Previous experience refers to the time spent gaining work experience in related occupations or activities required for the competent performance of the tasks in an occupation.
It is measured in months or years. On-the-job training refers to the amount of training required after commencing work in an occupation for competent performance of the tasks in that occupation. It is measured in months or years, and may be undertaken at the same time as formal training. ANZSCO does not measure the skill level of an individual, rather it refers to the level of skill that is typically required to competently perform the tasks of a particular occupation.
Skill level is an attribute of occupations, not of individuals in the labour force or of particular jobs. It is irrelevant whether a particular individual working in a job in a particular occupation has a certain amount of training or a particular level of competence or not. For example, a person who spreads mortar and lays bricks for a living has the occupation Bricklayer, regardless of whether he or she is an exceptionally competent bricklayer with many years of experience and post-trade qualifications, or an inexperienced bricklayer with no formal qualifications and a low level of competence.
The skill level of the occupation Bricklayer is determined on the basis of that typically required for competent performance. In determining the skill level of each occupation in ANZSCO, advice was sought from employers, industry training bodies, professional organisations and others to ensure that the information is as accurate and meaningful as possible. The determination of boundaries between skill levels is based on the following definitions.
At least five years of relevant experience may substitute for the formal qualification. At least three years of relevant experience may substitute for the formal qualifications listed above. At least one year of relevant experience may substitute for the formal qualifications listed above.
In some instances relevant experience may be required in addition to the formal qualification. For some occupations a short period of on-the-job training may be required in addition to or instead of the formal qualification.
In some instances, no formal qualification or on-the-job training may be required. The concept of skill specialisation Skill specialisation is defined as a function of: field of knowledge required materials worked on, and goods or services produced or provided.
Field of knowledge required refers to the subject matter knowledge that is essential for satisfactory performance of the tasks of an occupation. Tools and equipment used includes all forms of plant, machinery, computer-based equipment or hand tools used in the performance of the tasks, as well as intellectual tools such as personal interaction, and art or design techniques.
The term plant is used to describe mobile or stationary equipment which is large in size, performs several related functions, and is usually controlled by an internally located operator. The term machinery is used to describe stationary equipment which is not as large as plant, performs one processing function and is usually controlled by an externally located operator. The term hand tools is used to describe equipment which is small enough to be moved by one person.
Materials worked on refers to materials of both a tangible and abstract nature which are extracted, processed, transformed, refined or fabricated as an essential part of the tasks performed. Examples of materials worked on include wood, metal, livestock, accounting data, text, people and organisations. Goods or services produced or provided refers to the end product of the performance of the tasks of an occupation including physical goods, personal or other services, or abstract goods such as a software application or statistical information.
Employability skills In developing the skill specialisation criteria for ANZSCO, employability skills were considered as a possible additional dimension of skill specialisation. There are two facets to employability skills, personal attributes such as loyalty, commitment and motivation, and generic skills, including communication, team work and problem-solving. Employers are increasingly using employability skills in conjunction with technical or job-specific skills when assessing the suitability of an individual for a particular occupation.
Since these employability skills are applicable to most occupations, it was decided not to include them as classification criteria for ANZSCO. Further discussion on employability skills can be found in Appendix D. Statistical balance As a general principle, a classification used for the dissemination of statistics should not have categories at the same level in its hierarchy which are too disparate in their population size.
That is, similar numbers of real world entities should be classified to each category at a particular level. This approach serves to minimise large variations in standard errors and the suppression of cells in statistical tables at particular levels of the structure when using output from sample surveys.
It also allows the classification to be used effectively for the cross-tabulation of aggregate data. Categories which have been defined to reflect the real world, however, will not always be statistically balanced. To force categories to conform to size limitations would mean that the categories would not always be meaningful or useful.
The following minimum and maximum size guidelines were considered in designing the categories at each level of ANZSCO.
