How it connects#

O*NET also lists (no page here yet): Computer Numerically Controlled Tool Operators · Milling and Planing Machine Setters, Operators, and Tenders, Metal and Plastic · Tool and Die Makers · Lathe and Turning Machine Tool Setters, Operators, and Tenders, Metal and Plastic · Computer Numerically Controlled Tool Programmers · Multiple Machine Tool Setters, Operators, and Tenders, Metal and Plastic · Aircraft Structure, Surfaces, Rigging, and Systems Assemblers · Tool Grinders, Filers, and Sharpeners

What O*NET rates highest#

From O*NET 51-4041.00 (Machinists). Ordered by O*NET's importance rating; the words are O*NET's own scale anchors.

Each task in O*NET's terms#

O*NET describes work as detailed activities. Each of this page's 4 tasks is matched only against the activities O*NET lists for this occupation, with a stated fit; 4 match at least one. The alignment and its fit are this site's judgement, made task by task by its AI agent (Claude) on 2026-09-26; O*NET does not align tasks like ours. The activity names are O*NET's, the translations ours.

Our task judgements#

Sources and rules#

• Each block says where it comes from: this site's own judgements, O*NET, the U.S. Department of Education's CIP–SOC crosswalk, the European ESCO classification and its official crosswalk to O*NET, the ILO's ISCO-08, Singapore's SSOC 2024, or something computed mechanically from those. Nothing on this page is a rating we made up.
• O*NET's importance ratings are used only to order and shorten the lists. They are never combined with this site's impact index or evidence counts.
• The fit between our page and an O*NET occupation is our judgement and is stated per code: same job, broader, part of it, or only the closest there is.
• The ESCO and ISCO-08 fits are derived mechanically from the official ESCO–O*NET crosswalk; where we override it, we say why in our data (for example, the crosswalk pairs radiologists with radiographers, which is a different job). The SSOC 2024 fit is our reading of the Singapore Department of Statistics' own titles and definitions. Official names are shown as their publishers write them; we do not translate them.
• Each task is matched only against the detailed work activities O*NET lists for the codes this page maps to. Where nothing fits, the page says why instead of forcing a match: work O*NET does not describe yet (used only for tasks we judge to be emerging), or nothing in O*NET's list for this occupation. An alignment never changes a task's direction, its basis or the impact index.
• Rules are read only from this site's verified records. A rule's official name must appear word for word in a record that reads it, so no name is made up; a policy mandate is read only as 'must', 'must not' or 'funds', because 'should' and 'in principle' are not a mandate. Reading a rule never changes a task's direction, its basis or the impact index.
