How many charter schools need substitute teachers?

There are 57 charter schools in Idaho, serving nearly 22,000 students and employing roughly 2,100 people. Most charter schools need substitute teachers throughout the school year.

ICSN has created a charter school substitute teaching pool with twelve charter schools statewide, in both the Treasure Valley and Southeast Idaho.

Substitute teaching applications are accepted year-round.

What is the pay for a substitute teacher?

Charter schools pay substitute teachers a wage competitive with their surrounding districts. Subs will generally be paid in full-day (over 4 hours) or half-day (4 hours or less) increments, and are paid monthly by each individual school. Check with each school for more details, as they may have varied positions and pay rates.

What is a criminal history background check?

All substitute teachers must undergo a criminal history background check before being allowed to work in a school. You will be fingerprinted and a check will be run through three agencies: the FBI, the Idaho Bureau of Criminal Identification, and the Statewide Sex Offender’s Registry. You will not be approved to work as a substitute teacher until we receive a clear criminal history.

The Idaho State Department of Education performs criminal history background checks for all public schools. The cost is $27.00 and is paid by check to Idaho State Department of Education.

Criminal history background checks must be completed every five years.


Three forms are needed for fingerprinting. These will be mailed to you when you are selected as a substitute teacher for the ICSN substitute pool. The process takes approximately 10 business days and the cost is $10.00.
