LAS VEGAS — Enrollment in IICRC Water Restoration Technician courses increased 35 percent in 2025 compared to 2024, as insurance carriers and property managers increasingly require WRT certification as a condition of preferred vendor status or contract eligibility, according to IICRC enrollment data.
The WRT certification, which covers the science of water damage, psychrometrics, drying principles, and the IICRC S500 standard, has become the baseline credential for water damage restoration technicians. Several major insurance carriers now require that all technicians working on their preferred vendor network hold current WRT certification.
The surge in enrollment is being driven by both new entrants to the industry and experienced technicians who previously worked without formal certification. The IICRC's expansion of online and hybrid training options has made the certification more accessible to technicians in rural areas and those who cannot take time away from work for multi-day in-person courses.
The IICRC reports that the average time to complete WRT certification has decreased from five days of in-person training to three days for the hybrid format, which combines online pre-study with a one-day hands-on skills assessment. The hybrid format is now the most popular delivery method for WRT training.
Industry observers note that the increasing carrier requirement for WRT certification is creating a two-tier market in the restoration industry, with certified technicians commanding higher wages and having access to a broader range of work opportunities than uncertified workers.
