Evaluating Self-Perceived Benefits of Credentials in the Building Design and Construction Community: CPC, LEED-AP, and DBIA


Previous research in the building design and construction community has examined the benefits of gaining individual certifications but no research has been found that evaluates multiple certifications in the same industry. The purpose of this research was to determine if statistically significant differences existed between the self-perceived value of the Certified Professional Constructor (CPC) certification, the Leadership in Energy and Efficient Design Accredited Professional (LEED-AP) accreditation, and the Design Build Institute of America's Design-Builder designation (DBIA). Researchers evaluated the results of three previously completed surveys. The researchers were able to analyze 203 out of 527 (39%) responses from CPCs, 9,060 out of 46,332 (22%) responses from LEED-APs, and 155 of 631 (24.5%) responses from DBIAs. A one-way analysis of variance (ANOVA) was utilized to determine whether statistically significant differences existed between the three groups mean scores on eight impact questions. Results indicated statistically signifigant (0.05 alpha) difference between the groups on seven questions. On five of these seven questions, the mean scores for CPCs were significantly lower than LEED-APs and DBIAs. These results may be used by the credentialing organizations to measure their competitiveness and by those seeking certification to identify the potential benefits of certification.
