Interests

The OaSIS uses the Holland Codes to describe the work-related interests. According to the Holland model, people work best in work environments that match their preferences, which means that people and work environments can be matched for a best fit. Occupational environments in Holland’s theory are described according to a combination of main interests and the activities they represent. There are six interests in the Holland typology: Realistic, Investigative, Artistic, Social, Enterprising and Conventional. All occupations in OaSIS have up to three interests assigned to them.

Interests

Preferences for work environments and outcomes.

Interests profile: RIC

Realistic (R)

Realistic occupations are characterized by the dominance of activities that entail the explicit, ordered or systematic manipulation of objects, tools, machines and animals. Many of these occupations do not involve a lot of paperwork or working closely with others.

Investigative (I)

Investigative occupations are characterized by the dominance of activities that entail the observation and systematic or creative investigation of physical, biological, or cultural phenomena. These occupations require an extensive amount of thinking and frequently involve working with ideas, searching for facts and figuring out problems mentally.

Conventional (C)

Conventional occupations are characterized by the dominance of activities that entail following sets of procedures and routines. These activities may include systematic manipulation of data, such as keeping records, filing materials, reproducing materials, organizing written and numerical data according to a prescribed plan, and operating business and data processing. They often require following a clear line of authority and usually involve working with data and details more than with ideas.

Employment requirements

Employment requirements includes the education, training, certifications and the knowledge required to work in each occupation. The Knowledge category displays up to 10 descriptors in descending order based, firstly, on their attributed ratings by the level of proficiency, and secondly, in alphabetical order. The whole list of Knowledge descriptors and their ratings can be expanded at the bottom of each page.

Education, certification and licensing

Linkages Between ESDC Skills Models and Frameworks
 
ESDC makes available a dictionary of over 300 terms (or descriptors) and definitions, known as the Skills and Competencies Taxonomy (SCT). Descriptor information from the Taxonomy is used in the Occupational and Skills Information System (OaSIS).
 
While there is general commonality of meaning between the descriptors in the SCT and the Skills for Success model, there are some differences in their definitions due to their distinct purposes. The Skills for Success Model [9 broadly defined skills] identifies the skills that are universally applicable. The SCT displays specific skills and competency requirements for 900 occupations. Users of the Skills for Success Model and Essential Skills content may find competency information from the Taxonomy and the OaSIS to be complementary.
 
Stay tuned to this section for more information and updates regarding linkages between the Skills for Success model and the OaSIS.
