Appendix 4. Content Updates Since Release 4.0

O*NET 29.1 Database

O*NET 29.0 Database

Beginning with the 29.0 release, task statements are considered relevant and retained as part of an occupation’s task statement list if they have a relevance rating of 25% or higher. The minimum relevance in previous releases was 10%. This impacts the 80 occupations with updated task ratings, as well as 466 task statements across an additional 228 occupations.

O*NET 28.3 Database

O*NET 28.2 Database

For additional details on the related occupations updates, see Updates to Related Occupations for the O*NET Program Using the O*NET 28.0 Database in our Reports and Documents area.

Previous releases rounded Standard Error and other metadata to 2 decimal places, resulting in a rounded value of zero when the actual value was very small but greater than zero. This release increases the precision to 4 decimal places, providing additional clarity in these cases.

O*NET 27.1 Database

This release updates the approach to identifying “Hot Technologies” and introduces the concept of “In Demand” technology skills.

The purpose of the two designations is to enable O*NET customers to learn which technology skills employers in the US economy are presently emphasizing and searching for while recruiting employees. For additional details on the Hot Technology and In Demand designations, see Hot Technologies and In Demand Technology Skills within the O*NET System in our Reports and Documents area.

O*NET 27.0 Database

O*NET 26.3 Database

The newly added Related Occupations file replaces the “Career Changers Matrix” and “Career Starters Matrix” files, which have been removed from the database. These related occupations are developed using an approach which includes three important contributors to occupational similarity: what people in the occupations do, what they know, and what they are called.

For additional details on the Related Occupations project, see Developing Related Occupations for the O*NET Program in our Reports and Documents area.

O*NET 26.2 Database

O*NET 26.1 Database

For additional details on the Level Scale Anchors update, see O*NET Level Scale Anchor Updates: Knowledge and Generalized Work Activities in our Reports and Documents area.

This release transitioned technology skills and tools information to an organizing structure based on the latest version of the United Nations Standard Products and Services Code (UNSPSC). For details, see UNSPSC Reference.

In this release, the Content Model Reference file was updated to minimize wording and grammar differences between the O*NET Database and O*NET Questionnaires. These updates also affected other download files where element names or descriptions are included. For more information on the role of questionnaires in our data collection process, see O*NET Data Collection Overview.

O*NET 25.3 Database

O*NET 25.2 Database

The 25.2 release of the O*NET database includes the identification of technology skills related to distance learning and remote training. During the current COVID pandemic, schools, teachers, students, families, and businesses often rely on a wide variety of emerging technologies to navigate the challenges of decentralized education and work environments. For an initial listing of over 50 related technology skills, see O*NET Resource Center — Distance Learning & Remote Training.

O*NET Hot Technologies were also updated in this release, leading to the following database enhancements:

O*NET 25.1 Database – Updating the O*NET-SOC Taxonomy

The O*NET-SOC 2019 taxonomy structure has been revised based on the transition to the 2018 SOC. The O*NET 25.1 Database, which incorporates the new O*NET-SOC taxonomy, includes 1,016 occupational titles, 923 of which represent O*NET data-level occupations.

A technical report, Updating the O*NET-SOC Taxonomy: Incorporating the 2018 SOC Structure, is available which describes the new O*NET-SOC 2019 taxonomy structure. The overall relationship between the O*NET-SOC 2019 and the 2018 SOC is summarized. Code, title, or description changes that occurred from transitioning to the new 2018 SOC structure are detailed in the report. The new O*NET-SOC 2019 structure also includes four cybersecurity-related new and emerging occupations.

For a graphical overview of the new structure see: About the O*NET-SOC 2019 Taxonomy

Data from the O*NET 25.0 database (O*NET-SOC 2010) has been incorporated into the new O*NET-SOC 2019 taxonomy, including the new O*NET-SOC codes, titles, and descriptions. In the 25.1 release, taxonomy-related updates include:

A total of 874 occupations include data on Knowledge, Skills, Abilities, and other descriptors in this release. 53 of these occupations include data aggregated from one or more predecessor O*NET-SOC 2010 occupations. In these cases, data is marked with “Analyst - Transition” in the Domain Source column. Some ratings, including Education, Training, and Experience ratings, are not available. These occupations will be updated through the O*NET Data Collection program with data from job incumbents and occupation experts, replacing the transitional data in future releases of the O*NET Database.

Apart from the taxonomy changes, alternate titles were added or revised for 370 occupations, as part of the ongoing effort to improve and update the O*NET Database.

O*NET Database 15.1 – Updating the O*NET-SOC Taxonomy

The O*NET 15.1 Taxonomy Preview Database aligns the O*NET-SOC taxonomy with the 2010 SOC (Office of Management and Budget, 2010). Data from the O*NET 15.0 database (O*NET-SOC 2009) has been incorporated into the new O*NET-SOC 2010 taxonomy, including the new O*NET-SOC codes, titles, and descriptions. For 838 data-level occupations, the data remains unchanged from its publication in the O*NET 15.0 database. This occurs where the O*NET-SOC 2010 occupation is a clear successor of the O*NET-SOC 2009 occupation. There are 6 exceptional cases where data has been aggregated from one or more source occupations.

Changes made to the O*NET 15.1 Database are summarized below. A historical summary of all database changes since the release of the O*NET 4.0 Database are provided in O*NET Database Content Changes 5.0 - 15.1. In the O*NET 15.1 Database, 545 occupations had changes to their code, title, and/or description that are reflected in the Occupational Data file.

This new taxonomy contains an additional 153 New and Emerging (N&E) occupations. For more information about N&E, see New and Emerging Occupations of the 21st Century: Updating the O*NET-SOC Taxonomy (March, 2009).

O*NET Database 5.0 – First Data Collection Release

The April 2003 release of the O*NET 5.0 Database represented the first database release to incorporate data from the data collection program. It was the first of planned semi-annual updates of the database to update all O*NET-SOC occupations.

Release 5.0 contained the following:

O*NET Database 4.0 – Final Analyst Database

The O*NET 4.0 database represents the final version of an “analyst ratings only” O*NET Database. The ratings for each of the 900+ O*NET-SOC occupations in the 4.0 database were developed by occupational analysts and every occupation contains ratings for the same range of descriptors. The ongoing O*NET data collection program is gradually replacing these original analyst ratings with ratings derived primarily from job incumbents, as well as, ratings from an updated analyst procedure. The database structure and content changes incorporated in 4.0 were made to make the database consistent with data collection program. For more details about these changes, please refer to Summary of O*NET 4.0 Content Model and Database (October 2001) (http://www.onetcenter.org/resData.html#summary)
