Newborn hearing screening and the JCIH timeline

Congenital and early-onset hearing loss is common enough, and consequential enough for language development, that most of the United States screens every newborn's hearing before hospital discharge. A screening result by itself does not help a child; what matters is how quickly a failed screen turns into a confirmed diagnosis, and how quickly a confirmed diagnosis turns into intervention such as amplification and early intervention services. The Joint Committee on Infant Hearing, JCIH, publishes the timeline that most state early hearing detection and intervention programs are built around, and it is usually described by three numbers in a row.

The benchmark, in place since JCIH's 2007 position statement, is 1-3-6: hearing screening completed by 1 month of age, a full diagnostic audiologic evaluation completed by 3 months of age for any infant who does not pass the screening, and enrollment in early intervention services by 6 months of age for any infant confirmed to have hearing loss. Screening itself typically happens well before 1 month, often before hospital discharge in the first days of life; the 1 month mark is the outside limit for completing screening on infants who did not pass an initial in-hospital test.

JCIH's 2019 position statement kept 1-3-6 as the timeline used to measure state and national program performance, but it also set out a more ambitious 1-2-3 goal for individual children: screening still by 1 month, but diagnosis moved up to 2 months and enrollment in early intervention moved up to 3 months. The motivation was straightforward: every month a child with hearing loss spends without amplification or intervention is a month of missed access to language, and the 2019 statement pushed programs to compress the gap between a failed screen and actual support rather than treating 3 and 6 months as targets to be comfortable with.

In practice, 1-3-6 remains the figure most often quoted as the standard, and it is still what most state Early Hearing Detection and Intervention, EHDI, programs report against, while 1-2-3 functions as the aspirational goal that newer program improvement efforts are measured against.

The biggest obstacle to hitting either timeline is not usually the screening step, which most newborns already receive, but loss to follow-up: infants who fail a screening but never return for the diagnostic evaluation, or who are diagnosed but never make it into early intervention. Shortening the diagnosis and intervention deadlines, as the 1-2-3 goal does, is in part an attempt to reduce the number of families who fall out of the pipeline during a long wait between steps.
