Accuracy Measuring Engagement

How AER™ Measures Employee Engagement

  • AER™ measures employee attitudes towards the proven 15 drivers
    of engagement by calculating an index for each individual driver and
    generating an overall engagement index based on the correct weighting
    of each driver. Each leader has a statistical psychometrically sound
    AER™ engagement profile for his/her group that he/she can impact.

  • Each engagement driver is independently measured by empirically
    validated battery of questions. This method of attitude measurement
    ensures accuracy and enables leaders to conduct root cause analysis
    ​to improve attitudes toward each driver.

  • Engagement drivers, questions results, and AER Engagement Indexes are compared to our Critical Ranges based on over 15 million surveys thereby ensuring confidence of action.

Associate Engagement Research (AER™) is an empirically validated employee engagement survey that measures all 15 drivers of employee engagement which directly affect employee on-the-job effort. Unlike any other survey, AER is based on Dr. Frederick Herzberg’s Motivation to Work Studies and calibrated for global use. This behavior-based instrument has been thoroughly researched, applied and developed over many years by Dr. Robert Brown, Dr. Lester Zerfoss and Ken Scarlett to directly connect 15 employee experiences (drivers) to behavior and the accomplishing of business outcomes. AER has been used by thousands of organizations to pro-actively and successfully manage their human resources long term.

Leaders and organizations are often distracted from managing the real drivers of employee engagement. Our research has shown that opinion questionnaires do little to improve employee engagement or quality of leadership because these surveys usually focus on generalized quick fixes that employees view as disingenuous and uncaring. Scarlett Surveys unique AER Engagement Index™ and Ratio is compiled by surveying all employees with the complete set of engagement drivers. You get the full picture: quality engagement psychometrics you can trust to improve relationships while improving business performance and strengthening leadership skill – by group and overall. Our AER Engagement Index™ and Ratios accurately describe the engagement level of each group while the in-depth drill downs into the 15 engagement drivers reveal what interactions or events need to change to improve engagement intensity. Thus, your organization is able to sustainably manage employee engagement. Leaders become masters of engagement using AER™.
