5 Best Technical Skills Assessment Tools (2021)

5 best technical skill assessment platforms - WeCP Blog

Technical skill assessments have transformed the recruiting process for companies and candidates alike – and you don’t need to take our word for it. Research conducted by the Aberdeen Group revealed some major insights – conducting skills assessment tests before hiring reduces turnover rates by 39% and increases the likelihood of employees exceeding performance goals by 24%.

Technical skill tests can be a recruiter’s best friend, but only if they’re designed right. A poorly designed skills test will fail to successfully evaluate candidates, and you might end up hiring someone unfit for the position. This is why it’s crucial to use the right technical skills assessment tool – we’ll take a look at the best ones in this piece.

What is a technical skills assessment tool?

A technical skills assessment tool is software that contains a rich library of technical assessment tests, including questions and answers for recruiters to screen and evaluate candidates.

The assessments created on these platforms are used to evaluate candidates before employment by technical recruiters and/or hiring managers.

Why are so many companies using technical skills assessments?

Companies used to be limited to resumes and portfolios as a means of screening candidates before interviews, which are adequate at best, and far from reliable. Then technical assessment tests popped up and changed the game entirely. 

Technical skill assessments have revolutionized the recruiting process, allowing companies to screen and evaluate candidates reliably and extensively. A custom skill assessment test goes beyond showcasing a candidate’s profile and provides realistic insights on how ready the person is to tackle real, on-the-job problems. Tech skill tests effectively save companies time, money, and resources when it comes to hiring – or even for assessing an existing employee’s fit for a different role. 

How do skill assessments compare to other assessment methods?

Skill assessments are not the only type of evaluation used by the hiring teams – job simulation resumes, and reference checks are all common assessment methods. The trouble with resumes and reference checks is that they don’t reveal the whole picture. A candidate and often their references will attempt to present the applicant in the best positive light. Unfortunately, this may not be the most accurate portrayal of the candidate’s skills and abilities. 

Job simulations, also known as work simulations, require candidates to perform tasks that the role requires in the workplace. These simulations are an effective evaluation tactic to understand how the candidate will perform in the real work environment.

Structured interviews are also an effective evaluation method, and they include a scoring system similar to that of skill assessments. The common denominator between the two methods is that they are both quantitative and can thus be reliably compared and contrasted. Moreover, recruiters can extract useful insights from the collected data.

Skill assessments have the added benefit of providing recruiters with the opportunity to reliably screen out candidates pre-interview. Thus, when it comes to tech hiring, skill tests take the cake to justify reliability, efficiency, and cost-effectiveness.

What are the types of technical skills assessment tests?

Skill assessment tests are of different types and are typically customized to evaluate a specific skillset required for the concerned role. A tech skill test may evaluate a candidate on their knowledge of a specific programming language or their understanding of certain algorithms, or on developer skills, among other things.

The best skills assessment tools let recruiters generate custom tests on-demand, so you can design an assessment to evaluate a specific skillset required for a given role. Skill assessments can be conducted pre-interview or during the interview, depending on whether you’re using them as a pre-screening tool or as a means of evaluation during the hiring process. 

The 5 best technical skills assessment tools

While skill tests are great, we mentioned earlier that you need the right kind of assessment to guarantee fair evaluation and the best results. Therefore, the ideal technical assessments tool should offer:

  • The ability to measure modern as well as legacy developer skills
  • Automation to minimize manual grading – through auto-evaluators and industry-leading compilers
  • Exceptional candidate experiences and custom branding opportunities for companies
  • Tests specifically tailored to various jobs and roles
  • Efficient qualitative score analysis
  • Seamless integrations with other hiring solutions
  • Unmatched data security for your candidate data
  • Video interviews with pair programming abilities
  • Comprehensive data insights, analytics, and reporting

Of course, not every tool will have all these features. So let’s take a look at the best skill assessment tools for tech recruiters and hiring managers and see which one wins out.

However, one drawback of using this tool is that it lacks AI-powered video proctoring and web proctoring features, which may lead to cheating.
