WDRO - What does WDRO stand for? The Free Dictionary
References in periodicals archive
WDRO is being used in classrooms when teachers reward students who have not behaved inappropriately for a whole period (rather than for any specific moment in the period, which would be MDRO).
While this procedure is slightly more accurate at such a small interval, it cannot be used with WDRO because it would not tell us whether behavior was occurring during the interval: it could only tell us what was occurring at the end of the interval.
