eNPS stands for 'Employee Net Promoter Score' and is based on the Net Promoter Score principals used by companies who want to gauge brand loyalty. With eNPS, your employees are your customers and how they feel towards your company is their brand loyalty. To gauge this, an eNPS survey will ask your employees one question:
‘On a scale of 0-10, how likely are you to recommend [brand/company name] to a friend?’
If they answer 0-6 then they are classed as a 'Detractor', 7-8 is a 'Passive', and 9-10 is a 'Promoter'.
One difference between NPS and eNPS is that you've got the ability to collect further feedback through the added, non-compulsory question:
‘Please tell us more about why you chose [score].’
