RFP questions for AI-driven assessment vendors: a 2025 guide

This document is a question bank for procurement teams shortlisting an AI-driven assessment vendor such as Selection Lab. Use it to draft RFP and tender questions for hiring assessments. It assumes you are assessing a platform that screens, tests or scores candidates and that you need evidence you can defend in an audit.

How to apply the checklist

Each question carries a priority: M (mandatory, pass or fail with evidence) or D (desirable, scored). Require every answer to cite an appendix. A statement without an attached artefact counts as a claim, not evidence.

Attach three conditions to the bid:

  • Every document is dated, versioned and signed off by a named owner.
  • The vendor names points of contact for security, privacy and scientific validation.
  • Marketing metrics are labelled as such, with sample sizes and methods.

Mandatory vendor disclosures (must-submit)

Request one compliance pack containing:

  1. Data processing roles (controller or processor) and the DPA template.
  2. Sub-processor list, retention schedule and data residency statement.
  3. Security architecture overview.
  4. EU AI Act evidence pack, including risk management artefacts and human oversight design.
  5. A live demonstration of the full flow: candidate journey through to ATS write-back.

Rationale: a missing item at bid stage is a reliable predictor of a missing item at audit stage.

Psychometrics: validity, reliability and norms

FAQ

Can game-based assessments promote diversity in the hiring process?

Yes, game-based assessments can support diversity by focusing on skills and behaviors rather than traditional criteria like résumés, which may contain unconscious biases. This gives candidates from diverse backgrounds a fairer chance to demonstrate their potential.

What is a game-based assessment?

A game-based assessment is a method that uses game mechanics to evaluate a candidate’s skills, competencies, and personality traits. While playing these games, candidates are assessed on aspects like problem-solving, cognitive ability, and behavior under pressure in an interactive way.

What are the advantages of game-based assessments?

Game-based assessments offer a more engaging and interactive experience for candidates, which can lead to a more positive perception of the hiring process—especially among certain groups. For employers, they provide deeper insights into both cognitive and behavioral traits, which traditional tests may miss. They also reduce the chance of socially desirable answers, as candidates tend to respond more authentically in a game environment.

How reliable are game-based assessments compared to traditional tests?

When well-designed, game-based assessments can be just as reliable—or even more reliable—than traditional tests. They assess a wide range of behaviors and cognitive abilities in a dynamic setting. However, the quality of these assessments varies greatly, so careful evaluation is essential.

How does a game-based assessment work?

Candidates participate in interactive games designed to measure specific skills and behaviors. Evaluation goes beyond just the final score—it also considers how the candidate makes decisions, handles challenges, and responds to different scenarios. These insights reveal underlying thought processes and behavioral patterns.

Are game-based assessments scientifically validated?

The main drawback is that many game-based assessments are relatively new and have not yet been extensively researched by independent academics. Providers often cite their own research, which is rarely externally validated. Without independent studies, the reliability of these assessments remains uncertain—something to keep in mind when selecting one.

How can game based assessments contribute to a better candidate experience

This can vary significantly by audience. The playful, interactive nature of game-based assessments can lower stress levels for some candidates compared to traditional tests. However, research shows that certain groups, especially those over 35, may find them more stressful. Men also tend to rate the experience more positively than women.

Can you practice game-based assessment?

You can familiarize yourself with the style of games used, but it’s difficult to "practice" for them in a traditional sense. These assessments are designed to measure natural reactions and authentic behavior, so repeated practice typically has less effect on performance than with traditional tests.

Will game-based assessments replace traditional tests in the future?

It’s likely that game-based assessments will become more common in hiring processes, but they probably won’t fully replace traditional tests. Both approaches have value and can complement each other depending on the role and the company’s needs.

How are the results of a game-based assessment analyzed?

Results are analyzed based on predefined criteria such as problem-solving ability, reaction time, and behavior under pressure. Advanced algorithms collect and interpret this data to provide a reliable, objective evaluation of a candidate’s strengths.

What kind of skills do game-based assessments measure?

They assess a wide range of abilities, including problem-solving, adaptability, decision-making under pressure, teamwork, and emotional intelligence. Depending on the design, they may also evaluate cognitive skills like memory, attention, and pattern recognition.

How long does a game-based assessment take?

Typically, these assessments last between 15 and 60 minutes, depending on the game’s complexity and the number of skills being tested. They’re usually shorter and more engaging than traditional assessments, making for a smoother candidate experience.

Are game-based assessments suitable for all roles?

They are especially effective for roles that require flexibility, creativity, problem-solving, and strong interpersonal skills. For highly technical or specialized roles, additional assessments may be needed to measure specific knowledge.

What’s the difference between a game-based and a gamified assessment?

A gamified assessment adds game-like elements (such as points or rewards) to a traditional test to increase engagement. A game-based assessment, on the other hand, is a standalone game designed specifically to evaluate certain competencies. The game itself is the primary evaluation tool, not just an enhancement.

How can a good onboarding process contribute to higher retention?

An effective onboarding process can contribute to higher retention by helping new employees quickly adapt to their role, the company culture, and expectations. By providing support and clear information from the start, their engagement is increased, and the likelihood of them leaving early due to feelings of being overwhelmed or lacking guidance is reduced.

What is the role of company culture in retaining employees?

Company culture plays a crucial role in employee retention. When employees feel heard, valued, and connected to the values and norms of the company, they are more likely to stay.

How do I measure the success of my retention strategy?

The success of a retention strategy can be measured by tracking retention rates and turnover rates, and by gaining insights from exit interviews. Additionally, employee satisfaction surveys and feedback from performance evaluations can provide valuable information about the effectiveness of the strategies applied.

What are the costs of a low retention rate?

A low retention rate can bring significant costs, such as increased expenses for recruiting and training new employees. Furthermore, the loss of experienced staff can lead to lower productivity, reduced knowledge transfer, and a negative impact on company culture.

How can I increase employee engagement?

To increase employee engagement, involve them in decision-making processes, regularly ask for their feedback, and recognize their contributions. Offering development opportunities and maintaining transparent communication can also contribute to greater engagement.

How can technology help improve employee retention?
