What is ASPE?

At ASPE, we know you want to have a successful, rewarding career in estimating. In order to do that, you need a proven path to career excellence. The problem is that you’re worried you don’t have the tools or knowledge to be the best in the business, which makes you feel like the path forward is unclear and rocky. We believe you deserve an inside track to a fierce competitive edge, and you shouldn’t have to figure out how to be great in your role all on your own.

We know what it’s like to have a thirst for knowledge and an ambitious spirit, which is why ASPE was founded in 1956 to educate, certify, connect and support estimators just like you. In fact, our Certified Professional Estimator (CPE) certification is the oldest accredited (through the CESB) certification classification for estimators in the United States. 

In addition, our Estimating Academy provides estimators with proprietary courses, and we work tirelessly to strengthen our industry and profession through standardization and credibility. Our nationwide network of members provides an unparalleled depth of knowledge and resources to any estimator, no matter where they are in their career.
