The robust, evidence-based process was developed and implemented in Aotearoa-New Zealand beginning in 2020. This work assessment process is meticulous and painstaking, using data and drawing on detailed interviews with workers and their supervisors. It delves deep, beyond the high-level language of job descriptions and task lists associated with a role to look at:

• Skills
• Responsibilities
• Effort
• Conditions of work

Comparator occupations – roles in traditionally male-dominated professions – are used as a reference point to compare different kinds of work and to help determine if a job is underpaid because of sex-based pay discrimination.
