What is ASHI Certification?

ASHI Certified Inspector
The ASHI Certified Inspector (ACI) credential is a distinguished designation awarded by the American Society of Home Inspectors (ASHI) to professionals who meet rigorous standards of competence, experience, and ethics.
In 2009, the National Commission for Certifying Agencies (NCCA) accredited this credential, ensuring that it meets high national standards for certification programs. ASHI has successfully renewed this credential with NCCA three times now, a five-year renewal, and it is valid until 2029.
Home inspectors who earn the ACI credential benefit from increased credibility, trust from clients, and recognition from real estate professionals. The NCCA accreditation adds further value, confirming that ASHI Certified Inspectors are held to the highest level of industry excellence. This designation can lead to more business opportunities, higher pay, and professional growth in a competitive field.
As part of the requirements for this accreditation process, we publish our annual statistics.

Why is the ACI credential accredited by NCCA?
Accreditation by the National Commission for Certifying Agencies (NCCA) ensures that the certification program adheres to national standards for competency, fairness, and rigor, providing greater credibility to both the credential and the certified professional.
For home inspectors, this means that the ACI credential is recognized as being backed by an independent, reputable authority, which can enhance their trustworthiness in the eyes of clients, employers, and industry stakeholders.
NCCA accreditation also signals that the certification is regularly evaluated and updated to reflect current industry standards, further reinforcing the commitment to excellence and ethical practices. This added level of assurance can lead to increased job opportunities, professional recognition, and career growth for ASHI Certified Inspectors.
To earn the ASHI Certified Inspector (ACI) credential, candidates must meet several stringent requirements.
These include passing the National Home Inspector Examination (NHIE), completing a minimum of 250 fee-paid home inspections that comply with ASHI’s Standards of Practice, and submitting reports for review and verification. Additionally, applicants must adhere to ASHI’s Code of Ethics and agree to ongoing professional development by earning 20 ASHI Continuing Education Credits on a yearly basis.
