Knowledge of engaging participants and local organisations, obtaining and recording consent and enrolment, handling refusal and exit respectfully, and protecting personal data so that it stays out of the graph.
Data and evidence quality
Knowledge of structured field capture, geotagged and timestamped evidence, device metadata, observer role grading of evidence, restatement and withdrawal, and the assessment of records against their evidence.
Field team supervision
The competence to lead a field team: planning visits, checking enumerators’, evaluators’ and collectors’ records against their evidence, resolving disagreements on site, and deciding when a record should be restated or withdrawn. Required to act in the supervisor role.
Household waste service operations
Knowledge of how a door-to-door or communal collection service runs: service points, containers and tags, collection rounds, service outcomes and service status, missed-service follow-up, and what a completed, evidenced piece of service work is.
Informal-sector inclusion and labour
Knowledge of working with informal waste pickers, cooperatives and contractors: how collectors are enrolled and recognised, safe and fair working conditions, and the line between evidenced work and remuneration, which is outside the standard.
Landfill and residual disposal
Knowledge of residual waste handling and disposal: transfer stations and landfills, weighbridge and disposal records, what counts as landfilled versus stockpiled, and the regulatory standing of a disposal facility.
Local area knowledge
Familiarity with a particular place: years resident, languages spoken, ability to find one’s way, membership of local organisations. Objectively testable and place-specific; a score is meaningful only for the census place or municipality it was earned in.
Material recovery and recyclate markets
Knowledge of sorting, weighing and grading recovered material: the material category hierarchy down to resin or grade, grading and moisture and contamination, scale practice, how offtakers receive material, and what evidence shows that mass reached a recovery destination.
Organic waste treatment
Knowledge of composting and other treatment of the organic stream: feedstock, process control, treated output, losses, and how treatment is evidenced and distinguished from disposal.
Source separation and behaviour change
Knowledge of separation streams, how participants learn and sustain separation at source, what training achieves, how separation quality and contamination are rated, and the limits of inferring behaviour from a single observation.
Survey and monitoring design
Knowledge of sampling frames and monitoring plans, scheduled visits and their outcomes, stratified estimation, rates and their denominators, service periods, and the limits of what a monitoring period can support.
Waste characterisation and sampling
Knowledge of sampling and sorting a waste stream into material categories to establish its composition: sample design, sample size, representativeness, safe handling, and recording uncategorised mass honestly.
