Pay Gap Analytics


The requirement for employers to report on their gender pay gaps means that Human Resources departments now require statistical expertise to measure, interpret and close their pay gaps. We know that this will take HR professionals out of their comfort zone but helping non-statisticians use statistics properly is at the core of what we are about. We are experts in pay gap analytics for all protected characteristics including gender, ethnicity and disability and offer these 4 services.

Close your Pay Gaps with Key Driver Modelling

We dig deep into your payroll data to identify the key drivers of your pay gaps. The result is a statistical model using a large number of variables such as pay band, seniority, job function, location, etc which can be used to identify the priority areas for closing your gaps. Click here to see an example of Key Driver Modelling can give you.

Understand your Pay Gaps with Pay Gap Analytics Training

We run training courses in basic statistics which are designed for non-statisticians such as HR professionals working on pay gaps. Our courses will show you how to perform the relevant calculations in Microsoft Excel, how to interpret what they mean for you and how to incorporate these in an action plan to close your gaps.

Tackle Pay Gap Issues with Independent Expert Advice

Has your gender pay gap data uncovered an issue that could have legal ramifications? Need an expert independent statistician who can testify whether the data supports or contradicts a claim of discrimination?  We have experience of acting as an expert witness in discrimination cases and we know how to testify and explain complex data in simple language that can be easily understood by non-statisticians.  Click here to see a video of our founder testifying about gender pay gaps.

Verify Equal Pay Compliance with a Statistical Audit

The requirement to pay men and women equally for doing the same job is not the same as gender pay gap but we are able use pay gap analytical methods to scrutinise your payroll data and identify potential pay differentials that need further investigation. Our audits are led by an accredited Chartered Statistician and the output will be a statement certifying whether or not statistical discrepancies in your payroll are present.
