Evo Analytics calculates professional experience using two related measures: Previous external experience and Weighted work experience. These fields give context to an employee’s career background by distinguishing between external roles and roles within your organisation.
Previous external experience
Calculated as the number of months between an employee’s 18th birthday and their start date with the organisation.
Assumes an employee began their professional career at age 18.
Weighted work experience
Weighted work experience provides a balanced measure of professional experience since the age of 18, applying different values to internal and external roles.
Weightings applied:
Current role experience = Months × 1.0
Previous internal experience (other roles within the organisation) = Months × 2/3
External experience (roles in other organisations) = Months × 1/3
Formula
Weighted Work Experience = (Current role months × 1.0) + (Previous internal months × 2/3) + (External months × 1/3)
Example calculation
Employee profile
Current role: 12 months
Previous roles in same organisation: 18 months
External experience: 30 months
Step 1 – Apply weightings
Current role: 12 × 1.0 = 12.0
Previous internal: 18 × 2/3 = 12.0
External: 30 × 1/3 = 10.0
Step 2 – Add together
12.0 + 12.0 + 10.0 = 34.0 months
✅ Total weighted work experience = 34.0 months
