How Assess and Recommend can Unlock your Potential
What is Assess and Recommend? The Assess and Recommend feature was created with the end user in mind and helps determine the most appropriate content based on a learner’s knowledge and experience. The assessment leverages computer adaptive testing (CAT), which is a computer-based assessment that adjusts the difficulty of questions based on how a test taker answers previous questions. CAT is also known as tailored testing because it personalizes the test to the test taker's ability level. Having a more personalized assessment allows for a more personalized recommendation. Customized learning paths – NICE Framework One of the best things about the Assess and Recommend feature is that it creates personalized learning paths aligned to NIST's Workforce Framework for Cybersecurity (NICE Framework). The NIST NICE Framework, or NIST Special Publication 800-181, provides a structured guideline for defining and categorizing cybersecurity work roles, knowledge, skills, and abilities (KSAs). It aims to standardize the language around cybersecurity tasks and roles, enhancing workforce development, training, and alignment between job requirements and individual qualifications. Unlike traditional training programs, which tend to be the same for everyone, Immersive Labs uses assessment data to identify which roles in the NICE framework are most applicable to you. This means users focus on what they need to learn, rather than wasting time on topics they already know. As users upskill, they can retake assessments to receive new recommendations that match their evolving skill level, keeping training relevant and engaging. This dynamic approach is essential in a field where staying current is critical. By aligning with the NIST NICE Framework, the learning paths are tailored to specific roles, such as SOC analyst, pentester, or cyber professional, making the training even more effective. Benefits for organizations and users For organizations, the Assess and Recommend feature is incredibly valuable. It gives a clear picture of the team’s overall skills, strengths, and weaknesses. This information is crucial for planning targeted training, using resources wisely, and strengthening the organization’s cybersecurity defenses. Additionally, by promoting continuous learning and development, organizations can improve employee satisfaction and retention. Employees are more likely to stay with a company that invests in their growth, recognizing the importance of updated skills for job security and career advancement. Where can I Find this Feature?
