This study employed mail survey using structured questionnaires
based on the Learning Organization Survey (LOS) developed by
Goh and Richards (1997), and the Dimensions of LO Questionnaire
(DLOQ) developed by Watkins and Marsick (1997). As both
instruments were not originally designed for studies involving the
non-profit sector, in order to adapt the instruments for use in this
study on non-profit sector, additional items derived from literature
review were established to examine the independent variables in
reference to the human social service NPOs in Singapore
