Why are Leadership Assessments Important?

“If you cannot measure it you cannot improve it”

– Lord Kelvin

Leadership assessments are one of the most common tools for talent assessment and development. But why are leadership assessments important? Well, as Lord Kelvin said, if you can’t measure it, you can’t improve it. Leadership assessments allow leaders to see and quantify the strengths of their team, which can help them to delegate, assign roles, and manage talent more effectively. Leadership assessments can also be used to identify development opportunities. This allows leaders to coach direct reports and create targeted activities through which they can learn. Leadership assessments, therefore, are a significant addition to other methods of talent selection and development.

What are the benefits of leadership trait assessments?

Studies have demonstrated the tangible benefits of using assessments for things such as leadership and talent development. The use of talent assessments has been shown to result in[i]

  • Revenue increased by 36%
  • Resources reduced by 40%
  • Time-to-Hire Reduced by 40%
  • Tenure Increased by 25%

Leadership assessments are also important because they:

  1. Add objectivity
  2. Save time
  3. Add standardization to the process
  4. Are easy to scale
  5. Increase self-awareness
  6. Improve employee motivation and engagement

Leadership Assessments Add Objectivity

Leadership assessments add objectivity to the talent development process because scores are given by a neutral, unbiased party. A strong assessment should be valid and reliable, providing measures that are accurate and predictive of an individual’s leadership potential. While references and recommendations can be a great starting point, leadership assessments provide added value in that they are not influenced by personal experience.

Leadership Assessments Save Time

Unlike personal talent reviews – which can take weeks, if not months – leadership assessments can be administered quickly and efficiently. This makes them a great option for large groups. Online assessments especially have the benefit of saving organizations a lot of time and human resources. They can be done by multiple people at the same time, do not require anyone to administer or grade the assessment, and often provide a report of results immediately upon completion. To see an example, check out SIGMA’s Leadership Skills Profile – Revised (LSP-R) and the sample report.

Leadership Assessments Add Standardization to the Process

Another benefit of using leadership assessments is that they add standardization to the process. Rather than coming up with new ways to quantify and measure talent, each leader can assess themselves and their team using the same tool. This makes collaboration and communication much simpler because everyone will be using a common language and a common system.

Leadership Assessments Are Easy to Scale

Because assessments help standardize a process, they also make the process much easier to scale. Talent development programs that are based on leadership assessments can easily be rolled out across other teams or departments. They have a much lower start-up cost in the way of time, human resources, and even budgets. They also require less administrative effort, because the assessment and subsequent development process is the same for everyone.

Leadership Assessments Increase Self-Awareness

Another one of the greatest benefits of leadership assessments is increased self-awareness. Assessments help people identify their strengths and development opportunities. This helps teams play to their strengths and be more intentional about pursuing opportunities for growth. Assessments can also help leaders uncover blind spots; things they might not have known or thought to ask about themselves. Increased self-awareness can boost confidence and lead to improved performance. It therefore not only benefits individuals themselves, but organizations at large.

Leadership Assessments Improve Employee Motivation and Engagement

Finally, perhaps one of the most significant reasons why leadership assessments are important is that they improve employee motivation and engagement. Using talent assessments shows employees that leaders want to invest in understanding their team. When paired with development efforts, this can be a significant source of encouragement for individuals. Studies show that one of the major reasons why people quit their jobs is because they feel their career path has been stalled (43%). Research has also found that 38% Gen Z workers (born after 1997) said they were looking for jobs with greater transparency around career path and development.[ii] Using leadership assessments to provide employees with that transparency and development can therefore significantly improve motivation and engagement, leading to better performance and lower turnover as a result.

Introducing the LSP-R

If you’re looking for a strong assessment to help you test your leadership skills, check out SIGMA’s Leadership Skills Profile – Revised (LSP-R). The LSP-R is a personality-based assessment of leadership skills that can be used to guide leadership development efforts. The test scores individuals on 50 leadership competencies including cognitive, personal, interpersonal, and senior leadership skills. Everyone who takes the LSP-R will automatically receive a Focus Report which includes a summary of scores and analysis of results, as well as templates and activities for creating a personalized development plan.
