Although no one looks forward to retaking exams, licensing and recertification are methods to not only see if we are maintaining standards, but also a way of restricting the market. When the supply of sonographers is scarce, the price(wages) of paying them will go up.
When employers have a difficult time filling positions, those “competitive” wages will increase to attract only those that are licensed. Currently some markets are saturated with sonographers due to the influx of ultrasound training schools. There are no jobs available locally for these new grads, nor are there any openings for seasoned sonographers. Making it more difficult to acquire or retain the fewer skilled workers(licensed) is what will drive wages up.
Personally, I wish it were effective immediately, as I would gladly accept a boost in income.
