"It is clear that mail-in balloting faces administrative questions before we can be confident that it is as reliable as the in-person voting methods," explains the Caltech-MIT Voting Technology Preport report.
Some work has suggested that the relative efficacy of different modalities may depend on the level of learning outcomes, with online and in person delivery methods being equivalent for lower level skills but in person preferable for higher level skills [ 10].
A flexible recruitment strategy might allow in-person recruitment, should other methods fail.

Cognitive debriefing interviews with patients followed a standard, in-person, in-depth interview method that has been developed for the SF-36v2 [22].
This means that for almost every moment of every day, a student receives the right content, at the right level, in the right grouping and through the right delivery method (in-person, independently, with a teacher, a tutor, via technology, etc).
