When it is flashing the speed posted is the limit
Whatever the normal posted speed limit of the road is.
It is posted.
A motorist is expected not to drive faster than the speed limit on the sign until the school has been passed.
In many locations that is the statutory speed. HOWEVER - the legal speed limit at that time and place is WHATEVER IS POSTED. Many school locations are posted with speed limits that are different from the 'usual' prevailing speed on that roadway.

The legal speed limit when driving in a school zone is typically 20 miles per hour.
The school zone speed limit when children are present is typically 20 miles per hour.
When children are present, the speed limit in a school zone is typically reduced to 20 mph (or as indicated by local signage) to ensure their safety. This limit is in effect during specific hours when children are arriving at or leaving school. However, the speed limit may vary based on local regulations, so it's important to pay attention to posted signs. In some areas, the speed limit may be lifted outside of designated school hours.
There is no minimum
The presence of children does not alter the posted speed limit, except when traveling within a 'school zone'. Speed limits are likely just 20 miles per hour in the school zone starting a short time before, during, and a short time after regular school hours. You should use common sense when driving in areas where children are present, regardless of a posted speed limit anyway. You should pay close attention and might want to lower your speed when you are near a public park, during the loading and unloading of school buses, or in neighborhoods with children out playing.
The speed limit through a school zone can vary depending on location. Usually, the speed limit is between 15 and 25 miles per hour.
