In order to strengthen policies based on evidence, a better understanding is needed of health worker choice and behaviour. This book tries to help fill that gap. Relying on unique survey data, it analyses the career preferences of future health workers in Rwanda, focusing on their sector preference, their willingness to work in a rural area, likelihood to migrate abroad, and readiness to work in a high HIV prevalence environment. The findings show that health workers are not as uniform as is often thought, and can 410 0$aWorld Bank e-Library. 410 0$aWorld Bank working paper ;$vno. 189. 606 $aOccupational health services 606 $aOccupational health services$xHealth and hygiene$zRwanda 606 $aMedical personnel$zRwanda 606 $aMotivation 606 $aHealth Personnel 606 $aCareer Choice 606 $aCareer Choice 607 $aRwanda 608 $aEvaluation Study. 608 $aStatistics. 615 4$aOccupational health services. 615 0$aOccupational health services$xHealth and hygiene 615 0$aMedical personnel 615 2$aMotivation. 615 12$aHealth Personnel. 615 22$aCareer Choice. 615 22$aCareer Choice. 676 $a362.10967571 700 $aLievens$b Tomas$01808853 701 $aSerneels$b Pieter M$0956936 701 $aButera$b J.
