Occupational licensing makes it illegal to work in an occupation before meeting state-mandated entry requirements that often include minimum levels of education and training, paying fees to the state, and passing exams. Nationally, 21% of workers are licensed.[1]

Licensing requirements for the same profession vary significantly across states. The 2023 State Occupational Licensing Index (SOLI) ranks states by the number of occupations that are licensed.[2] The SOLI database focuses on 331 occupations that are available in the Knee Center licensing database.[3]

Iowa’s SOLI ranking

In the 2023 SOLI, Iowa ranks 26^th nationally (with 1^st being the most burdensome). Iowa makes it illegal to work in 180 of the 331 occupations examined. This is 1 more occupation than the national average of 179 and more than 30 more than Kansas—the state with the fewest legal barriers (147) to working nationally.

Uniquely licensed occupations in Iowa

Among the 180 occupations that Iowa establishes minimum entry requirements to begin working, there are 23 occupations that are licensed in 20 states or fewer nationally. Table 1 provides a full list of these occupations and there is also a separate excel file with full details for interested readers.

Iowa is one of only 2 states to license certified prevention professional advanced and electrical sign installers. Iowa is also one of only 10 states to license animal breeders and one of 12 to license cemetery salespersons.

Why Licensing Reform is Important

By making it illegal to work in 180 occupations, and uniquely licensing at least 23 occupations, Iowa is imposing significant cost on its citizens.

Existing economic research suggests that occupational licensing raises prices by as much as 16%.[4] Licensing also reduces employment by as much as 27% by making it more difficult to begin working in licensed professions.[5] Nationally, it is estimated that occupational licensing results in 2 million fewer jobs being created each year.[6]

Although licensing may have historically resulted in some benefits to consumers[7], there is little evidence that it is helping consumers in the present. Recent work finds little evidence that occupational licensing is improving the quality of services provided to consumers in the US and Europe.[8]

In summary, Iowa currently places unique restrictions on its citizens to begin working. These restrictions are very costly and generate little to no measurable benefits for consumers. Following the lead of the majority of other states and choosing less restrictive ways to regulate and protect consumers would be in the best interest of Iowa citizens.
