Simple Work Requiring Little or No Judgment Is Not Synonymous with SVP 1 and 2

Under 20 C.F.R. § 404.1568(a), unskilled work is defined as work that can be learned on the job in 30 days or less, involving simple duties with little or no judgment. While the 30-day rule is a primary, objective threshold for identifying unskilled work, the core definition requires the work to be simple and require minimal judgment, corresponding to a Specific Vocational Preparation (SVP) of 1 or 2. 

Key Details on Unskilled Work & 30-Day Rule:

• Definition: Unskilled jobs require little to no judgment to perform simple duties.
• 30-Day Rule: If a job requires 30 days or less to learn, it is typically classified as unskilled.
• Skill Level vs. Training Time: Although 30 days or less is the threshold, the type of duties matters. Semiskilled or skilled work requires more than 30 days (often 1–6 months or more) to learn.
• Examples: Unskilled jobs include, but are not limited to, cleaners, laundry laborers, and certain packers.
• Past Relevant Work: Work that lasted fewer than 30 days generally does not count as "past relevant work" for disability analysis, as it is not considered long enough to have learned the job, even if it is simple.

Skills typically require more than 30 days to learn. The definition of semi-skilled work does not make that assertion:

Semi-skilled work is work which needs some skills but does not require doing the more complex work duties. Semi-skilled jobs may require alertness and close attention to watching machine processes; or inspecting, testing or otherwise looking for irregularities; or tending or guarding equipment, property, materials, or persons against loss, damage or injury; or other types of activities which are similarly less complex than skilled work, but more complex than unskilled work. A job may be classified as semi-skilled where coordination and dexterity are necessary, as when hands or feet must be moved quickly to do repetitive tasks.

The key takeaways from subsection (b) include:

• Alertness and close attention to watching machine processes
• Inspecting, testing or otherwise looking for irregularities
• Tending or guarding equipment, property, materials, or persons against loss, damage or injury
• Coordination and dexterity are necessary

The description of semi-skilled is broader than SVP 3 or 4. The may clause in the regulation permits the use of the four examples of work that is semi-skilled regardless of the training time.

Subsection (c) defines skilled work with the same kind of examples without a specification of training time or SVP:

• Judgment to determine the machine and manual operations to be performed in order to obtain the proper form, quality, or quantity of material to be produced
• Laying out work, estimating quality, determining the suitability and needed quantities of materials
• Making precise measurements
• Reading blueprints or other specifications
• Making necessary computations or mechanical adjustments to control or regulate the work
• Dealing with people, facts, or figures
• Abstract ideas at a high level of complexity.

SVP 1 or 2 are clearly elements of unskilled work. But SVP 1 or 2 are not definitive or co-terminus with the concepts of unskilled as that term is defined in 20 C.F.R. § 404.1568(a).

Don’t let anyone tell you that SVP 1 and 2 equals unskilled equals simple. 

It is not true.
