From PAPI to CAPI and Beyond
How do you monitor quality
with PAPI surveys?
– Rely on humans and ex-post
data analysis
Why would you use PAPI?
– cost
– familiarity
CAPI: can it be more than
fancy paper?
– Passive monitoring at multiple
management levels
– Quick turn-around for QC

Passive GPS- where the heck are we?
Quality Control for
geographic sampling
approaches
– Interviewers not
responsible for recording
their locations.
GPS coordinates can be
recorded multiple times
during an interview.
– Did the whole interview
take place at the
household?

Turnaround time is an
issue
– Some questions or all
interview review
Quality of audio
recordings
Consent has not been
an issue for surveys with
low-sensitivity questions.

Implementation
QC Feedback Loop
– Are we just collecting
more information, or are
we actually using it?
Willingness
– Contracts
– Competitive advantage
Ability
– Capacity building and
support (can’t set it and
forget it)
