What is a long-term substitute, and is it different?

A long-term sub covers one teacher's class for an extended stretch, and districts define it themselves. Keller ISD in Texas calls it more than 10 consecutive days for the same teacher and pays a higher daily rate, but only to subs with a bachelor's degree or a teaching certificate. California's 30-day emergency permit caps one sub at 30 days per teacher in a year.

The threshold and the pay change from place to place. At Keller ISD, if a long assignment is known ahead of time, the higher rate starts on day one; if a regular job runs past 10 days, it starts on day 11. A Texas-certified sub filling a vacant position can earn more from day 45. California's permit allows only 20 days per teacher in special education classes.

The work is different too. A day-to-day sub follows the plan that was left. A long-term sub is more often expected to plan lessons, grade, and talk with families, because nobody else is doing it. That is why some districts want more training or a license for long jobs.

Before you say yes, ask the school or the district's sub office how long the job runs, what rate you will be paid and from which day, whether you will plan and grade, and who you report to.
