Introduction: Dr. Eduard M. Albay is an author, reviewer, and evaluator of high school mathematics textbooks, work texts, and modules of the University Press First Asia, one of the leading publishing companies in the Philippines. He has authored four books in mathematics which are used all over the Philippines. He is currently a professor in Don Mariano Marcos Memorial State University – South La Union Campus, College of Arts and Sciences and College of Graduate Studies. Further, he also holds administrative positions such as Head of the National Service Training Program (NSTP) of the campus and research coordinator of the College of Arts and Sciences. He holds a doctorate degree in Philosophy in Mathematics Education, minor in Educational Administration. He is an acknowledged regional and national lecturer, speaker, and trainer, a prolific researcher, a published author, and a competent and efficient administrator. Speech Title: Performance Efficiency in Research of the Departments Of College of Arts and Sciences: Basis for a Research Capability Taining Program Abstract: This study determined the performance efficiency in research of the four departments of the College of Arts and Sciences in DMMMSU-SLUC using Data Envelopment Analysis (DEA) Solver during the years 2015 and 2016. It also determined the: (1) performance efficiency level of the departments in research; (2) peer groups and weights of the departments; (3) virtual inputs and virtual outputs or potential improvements of the departments; (4) research capability building training program that can be developed based on the results. Findings of the study showed that: 50% of the departments are fully efficient while the other 50% are inefficient in research. The fully efficient departments, BPSD and MADD, have their own college as their peers and weights in Research. The BPSD and MADD serve as peers for the inefficient HSSD and LD, respectively, with different weights to consider. Fully efficient departments do not have virtual inputs and virtual outputs. Only HSSD and LD posted virtual inputs and virtual outputs in the research input and output indicator. Based on the results, a CAS Capability Building Training Series was developed to sustain the performance in research of the College of Arts and Sciences and to achieve a better research performance for all the college’s departments.
