This study aims to assess knowledge retention of the graduates of the online graduate certificate on local development planning, land use management and disaster risk management (PDLOTGR, the abbreviation of the certificate's Spanish title). The certificate was offered to practitioners and faculty members of Latin American countries since 2016.

The authors reviewed the knowledge, attitude and practice (KAP) method to develop a specific approach, which included the preparation of a KAP survey, a composite KAP index and three sub-indices. The survey targeted two groups: (1) experimental group, composed of the certificate's 76 graduates, and (2) control group, comprised of 25 certificate's candidates, who had not yet undergone the training/intervention. The statistical analysis included a one-way multivariate analysis of variance to compare the mean scores on the KAP index and sub-indices for individuals in the experimental and control groups.

The study results showed significant differences in the knowledge sub-index between those who had completed the PDLOTGR training and those who had not, while the attitudes and practices sub-indices did not show significant differences. When using the KAP index, a statistically significant difference was also observed between the two groups.

Perceived knowledge assessment offers an acceptable and non-intimidating option for evaluating continuing education and professional development programs associated to disaster risk. It is particularly helpful in determining whether an intervention or program has a lasting impact. It is not, however, a substitute for direct knowledge assessment, and the use of other methods to evaluate the performance of a capacity building program's graduates.
