If you’re just starting to get your feet wet with substitute teaching, you’ll likely have a lot of questions:

“How do I prepare for my first day?”

“What are the requirements for becoming a sub?”

“Do I need a certification?”

We’re here to help you navigate the nuances of substitute teaching. Let’s explore the differences between certificated and classified substitute teachers and the benefits of each.

Certificated vs. classified subs

While regular teachers must be certified or working towards certification, substitute teachers have more flexibility. A certificated substitute teacher needs to earn a credential that proves they have the necessary knowledge and skills for the role. In contrast, classified substitutes do not require this credential.

Certificated substitute teachers:

• Must have a credential
• Have met specific educational and training standards

Classified substitute teachers:

• Do not need a credential
• May have fewer restrictions on initial hiring requirements

Benefits of earning a credential

Not all states, schools, or districts require a substitute teaching credential, but there are significant benefits to earning one:

1. Credibility:

• A credential demonstrates that you meet specific standards and are qualified to manage a classroom effectively
• Increases chances for career advancement

2. Flexibility:

• With a teaching credential, you’re qualified for a broader range of roles
• Access to more job opportunities, allowing for better role selection

3. Stability:

• Stand out from other substitutes and qualify for long-term assignments
• Pave the way for higher pay and job security
