Tier 2 surveys satisfy 3 criteria. First, because they do not cover Basic Interests (the criteria to be a Tier 1 assessment), they must at least measure industry-standard RIASEC Holland Code interests. Second, they must also measure at least one other dimension when making career matches (e.g., needs, aversion, or personality). Third, they must use appropriate item formats for efficient psychometric measurement.

Tier 3 surveys suggest career matches based solely on RIASEC Holland Code interests. They are usually short and often free. Tier 3 surveys provide less accurate career matches than the Tier 1 or 2 tools because they measure less stuff - only 6 scales. They are ideal for people who only want to spend 5 to 20 minutes answering items. If you are willing to spend more time or money, Tier 1 or Tier 2 tools can provide more accurate matches.
Note that TESTERLY® also offers a free Tier 3 assessment. By completing the first 5 minutes of the TESTERLY® Career Survey tool, you will be matched to careers based solely on your 6 RIASEC Holland Codes. There is no cost for that service. The key difference is that with the TESTERLY® service, you also have the option to complete additional materials to further improve your matches.

Tier 4 surveys commit a psychometric error by using forced-choice (ipsative) item formats for scales that should not use them. Forced-choice formats force respondents to choose between competing interests (e.g., would you rather play piano or build a house?). They differ from standard rating formats in which respondents rate their level of interest in each activity (e.g., How much would you enjoy building a house?). Compared to standard rating formats, forced-choice formats have major disadvantages:
Because of those major disadvantages, experienced psychometricians only resort to forced-choice formats when there is a compelling need to do so (e.g., to combat faking). There is no such compelling need in career interest contexts. Career interest respondents have little or no incentive to lie.
If anyone from these companies reads this review, I encourage you to update your items to industry-standard 5-point response scales instead of using forced-choice triads or tetrads. I would be happy to move your revised assessment to a different Tier.

Surveys in the bottom tier assign people into personality "types." Anyone within a certain "type" will receive the same career matches. Although the concept of personality types was popular in the early days of psychometrics (e.g., before 1960), it is no longer a scientifically valid or accepted practice. Modern Psychology measures people's interests and traits. Those interests and traits are inherently multidimensional such that any attempt to categorize someone as a single "type" of person is a gross and unnecessary oversimplification. In 2025, a person's career matches can (and should) be based on all their multidimensional interests and traits. In 2025, personality "types" should not be used for career matching.

Basic report
Recommendations for which service to use typically depend on your situation and needs. People looking for a free or short assessment would be best served by one service, whereas people looking for the most accurate matches would be best served by another. I'll provide those traditional use-case-specific recommendations below.
You might notice that I included TESTERLY® as one of the top options for each use case. There's a reason for that. When building the service, I put a lot of thought into how to design a service that I could confidently recommend for all use cases instead of just optimizing for one or two of them.
With matches available after just 6 items (1 minute), TESTERLY® offers the shortest assessment. Improved matches are available after 5 minutes.
The next shortest Tier 1 or 2 surveys are Job Bank Canada's (10 minutes per quiz) and the Career Cluster Interest Survey (10 minutes), followed by CareerHunter (15 minutes for interests), and the Jackson Career Explorer (20 minutes).
If you loosen criteria to include Tier 3 surveys that cover only RIASEC Holland Codes, 123test.com offers a 5-minute assessment. O*Net Interest Profiler's 20-minute RIASEC assessment is longer than others on this list, but it has excellent measurement and validation properties.
You can obtain free RIASEC-based matches and reports by completing the first 5 minutes of the TESTERLY® Career Survey. The key advantage over other free services is that you also retain the option to complete additional material to improve your matches.
US citizens looking for other free services should consider the O*Net Interest Profiler. It is sponsored by the US Department of Labor. O*Net Interest Profiler is an excellent and entirely free service that combines a thoroughly validated measure of RIASEC Holland Codes plus a wealth of resources for each career. For Canadians, the Job Bank Canada assessment is a similar free service sponsored by the government of Canada. Beyond those government-sponsored free services, Career Cluster Interest Survey, 123test.com, and the Princeton Review Career Quiz likewise have no material behind any paywalls.
For people willing to invest an hour into answering items, the TESTERLY® Career Survey should offer the most accurate matches because it:
The next best alternatives would be the other Tier 1 Surveys: the Strong Interest Survey, CareerHunter, Sokanu CareerExplorer, and Jackson Career Explorer.
Almost all career matching services offer some level of information on each career. They typically include a job description, list of duties, typical income, and required level of education.
When designing career pages, I tried to learn from existing services to make the pages at TESTERLY® the most comprehensive and digestible.
Other career pages I recommend include CareerHunter's. Their pages are designed well, though they are limited to 234 careers rather than the 900+ careers common to most services. Sokanu Career Explorer put a lot of effort into creating write-ups and resources for each career. I also highly recommend CareerOneStop, a service funded by the US Department of Labor. They have a wealth of information on each career. For Canadian residents, Job Bank Canada is the most similar government-sponsored service.
I intended for Testerly's $23 price for premium matches (beyond the free RIASEC matches) to be a bit crazy/disruptive. All other Tier 1 services charge double that or more. Even the for-profit Tier 2 surveys are more expensive! Consequently, I hope Testerly is a clear winner in value for money.
The next best values include the Strong Interest Survey ($40), CareerHunter ($80), and Morrisby Careers (£25). I also feel compelled to mention the O*Net Interest Profiler and Job Bank Canada. Both are government-sponsored services that provide excellent value for no additional cost to respondents (i.e., all costs are shared by taxpayers).
