How to Use Feedback Loops to Improve Assessments?

Assessments are a standard aspect of hiring, training, and assessing performance in today’s world of work. Organizations evaluate pre-employment tests, coding evaluations, employee development, and skill assessments - we use evaluations to help us make better decisions. However, even with the most robust assessment it is unlikely it will be perfect the first time you use it. The questions might be ambiguous, certain questions may be too hard or too easy to assess the desired role, and the performance on the assessment may not correlate to the job performance. That is one of the reasons feedback loops are valuable. 

A feedback loop is the process of iterative enhancement to improve a designed experience. A feedback loop provides you the mechanism for you to collect data and learnings from the performance on each assessment - synthesize the data and actionable insights - and then use that data, feedback and insights to make improvements to that assessment until you run it again. Instead of trying to take an assessment, and assess its effectiveness once it is completed, adding a feedback loop creates the opportunity to enhance assessments over time. 

Platforms such as TestnHire demonstrate how feedback loops can have so much value when used in assessments. With the ability to provide in-depth, topic-reported feedback, clear benchmark measures, and feedback to candidates post-assessment TestnHire starts to demonstrate a great deal of value to employers in terms of determining what's working and what's not. For example, if multiple candidates struggle with one part of the assessment, it may indicate the need to reframe or change the difficulty of the question. Conversely, if candidates find a portion of the assessment too easy, a different question could be added to assess more accurately.

Ultimately, feedback loops can ensure assessments will try to keep pace with real-world requirements. They can turn assessments into living tools that grow each time an assessment is used, creating a more predictive, reliable assessment for the candidate. In today's job market, where both accuracy and the candidate experience matter, feedback loops should be a requirement, not an option for continuous improvement and decision-making.

What does a Feedback Loop in Assessments Mean

A feedback loop in assessments is a cyclical process:

1. You assess (whether it is a pre-employment assessment, coding assessment, an interview, something else).
2. You gather information or feedback about the assessment (from candidates, from results, from metrics).
3. You examine the results: what functioned, what did not function, where test-takers failed to demonstrate competence, whether the assessment is predictive of what it was meant to predict (and did you ensure the rapacity of the necessary instructional features).
4. You amend the assessment if needed (modified questions, changes in the difficulty level of the assessment, clarifying instructions, remove unnecessary content).
5. Then you assess again using the assessment you improved.

Over time, the assessment is closer to the ideal: more valid (measures what it is supposed to measure), more reliable (consistent), fairer and more useful for decision-making.

The Importance of Feedback Loops (with TestnHire’s Guidance)

TestnHire provides multiple insights that clarify why feedback loops are advantageous when each of these components are executed effectively.

1. Brand and candidate experience: TestnHire suggests that providing candidates with feedback after assessments enhances the employer brand and increases re-application rates. This indicates that even candidates who do not get hired feel positive about the process if they are treated well with information.
2. Analysing results in depth: In the TestnHire platform, assessments are divided into sections, according to skills or topics (logical reasoning, programming, communication for example). This allows you to see from which skill areas candidates excelled, and where most candidates struggled. That is valuable feedback.
3. Setting benchmarks and customisation: TestnHire's guides also suggest the importance of establishing benchmarks around skill scores, defining what "good" and "average" is; to help you determine when to adjust the assessment if there are many too low or too high scores.

How to Build a Feedback Loop for Your Assessments

Here is an easy plan you can use, using ideas from TestnHire plus best practices to create feedback loops in your assessment.

1. Design the assessment well, with clear sections

Segment the test to logical skill areas, or logical topics (for example, communication, coding, logical reasoning) - TestnHire does this. 
Be sure each question or task is linked to what the job really needs. If you are hiring a developer, include areas on programming, data structures, etc. If it is a support position, maybe communication, problem solving.
 

2. Collect feedback / data after the assessment

There are different kinds of feedback/data that can be collected:

• From the candidates: What did they think or feel about the assessment - was it too difficult, was it unclear on instructions, was there not enough time, etc.
• From the results: The results with actual scores or performance results based on topic or question. Maybe many scored poorly on a particular question or almost everyone did well on another question–these are signals.
• From hiring outcomes: Look at the performance of those who passed the assessments and were hired. How are they currently performing? Are they doing well at the job? Are they retaining the position?

3. Examine the feedback/data closely

Take a look at the breakdown by topic/skill to see the weak spots. TestnHire, for example, will give you a report that shows which topic(s) candidates are weak in.

See if any questions were too easy (not discriminating) or were too hard at the 85% fail rate, possibly because too many people failed.

Examine if the test has bias or unfairness: are there groups that do considerably worse in particular answers? Is language and/or instruction ambiguous?

4. Provide feedback to candidates

Give candidates feedback on their strengths and areas of improvement. You can even give this feedback to candidates who do not pass; this can improve their learning. TestnHire states that providing feedback increases the candidate experience.
 

5. Adjust the assessment

From the feedback, make adjustments to the assessment:
 

• Eliminate or reword unclear questions.
• Change the weight of the question if many people failed a question that is not critical (simply not that important).
• Rebalance weight among sections; maybe one topic ended up being more predictive of job performance, so give that topic greater weight.

Clarify instructions or time limits, particularly if candidates complained or the data shows many candidates dropped off.

How TestnHire Facilitates Feedback Loops

To facilitate feedback loops, TestnHire has some features and practices, including:

• Skill/topic-based detailed reports: After an assessment, TestnHire provides a detailed report through skill or topic that indicates strengths and weaknesses in that skill/topic. This is beneficial for employers and trainers to know where training should be focused.
• Benchmarks/scoring guides: These can help set expectations around what a normal score would be in each skill area (score ranges that sound acceptable vs. unacceptable and excellent) and can guide users towards interpreting assessment results, etc.
• Feedback to candidates: TestnHire publicly acknowledges that providing feedback to candidates post-assessment is valuable for brand reputation and candidate behaviour (ie: more likely to reapply). Ultimately, feedback indicates that the assessment doesn't feel like a black box.

Conclusion

Feedback loops are necessary; they form the core of any strong and usable assessments. Without them, organizations risk using old and irrelevant tests which do not reflect true job requirements. By continuously collecting and assessing feedback from candidates, results, and hiring outcomes the assessments become refined, more fair, and more predictive.

This feedback loop demonstrates a distinct advantage by taking the organization through a continuous improvement throughout the entire hiring process. For the organization, feedback loops demonstrate to the organization what works, not to work on, and how well assessments predict hiring performance. For candidates, feedback demonstrates the candidates' opportunities for growth and often leaves a good impression of the organization, even at the conclusion of unsuccessful employment considered a success. As TestnHire demonstrates structured reporting, skill-based reporting, and post assessment feedback will do so much for improvement of assessments but also embeds employer branding.

Most significantly, feedback loops foster trust and confidence. Candidates feel respected because their voices are valuable, and employers feel confident because their decisions are based on improved data. With each cycle, the assessment system becomes more intelligent, more equitable, and aligned with the organization's objectives.

In a competitive hiring and selection environment, assessments are no longer one-off tools; they are living systems that need to evolve over time. Feedback loops are what keep assessments alive and relevant. By embedding feedback loops you build into the process each assessment provides you with much more than a signal of how to evaluate a candidate - and help make better future hiring decisions.
