ATR’s multi-layer Quality Assurance system takes advantage of its staffing structure which maintains a strict separation between project staff and quality assurance staff.

ATR’s policy for handling fraudulent data is one of zero tolerance. Data that does not successfully pass quality assurance checks will be automatically discarded and recollected. Where necessary, ATR will aim to oversample in each catchment area to ensure that sample size not be a constraint on the statistical validity of the findings. The figure below provides an example of the 16 primary elements of ATR’s quality assurance process. These steps are considered a baseline in all comprehensive studies and may be tailored and enhanced according to the specific needs of a project.
ATR utilizes NoteCam to geotag its photographs for quality assurance purposes. The tags include latitude, longitude, elevation, as well as a time stamp and the possibility to enter notes describing the subject of the photograph. Additionally, the service includes multicoloured text in the bottom right-hand corner verifying that the tag was produced by NoteCam.

Likewise, when conducting surveys, ATR collects GPS coordinates and time stamps at the start and end of data collection. This helps to ensure that the surveyors spent an appropriate amount of time conducting the interview and remained on site (rather than going somewhere to collect the GPS point but then leaving to fill in the survey on their own).
GPS coordinates from data collection

The figure below provides an example of an instance where ATR’s use of GPS tracking allowed for the identification improper data collection. The straight line obviously demonstrated a violation of ATR’s random walk sampling protocols. Upon auditing, further wrongdoing was identified and data recollected.

ATR has newly adapted ArcGIS online to verify the location of each enumerator and ensure diverse data collection in the target area.
