The relationships between employee assessment scores and critical outcome variables, such as job performance and turnover, are not always clear cut. It is important to understand that such relationships do not always follow the linear pattern that most assessment vendors assume. There are certain situations in which we are more or less likely to see that linear trend.
For example, as the economy continues to improve, we are seeing turnover rates on the rise. The reason being, there are more alternative employment options available to employees and they are often easily accessible via the internet. Employees literally have these alternatives at their fingertips. Under such conditions, we cannot make broad claims that hiring individuals based on top assessment scores will always lead to reductions in turnover.
