Substituting Rules
The 30/20 Day Rule
Cumulative Day Length Limit for Substituting
Title 5 §80025.3(a): Individuals who hold a valid document which required the completion of a bachelor’s degree & the basic skills requirement (i.e. requirements for Emergency 30-Day Substitute Teaching Permit) are authorized to serve as day-to-day substitutes. Individuals are allowed to substitute for no more than 30 days for any one teacher during the school year with one exception. Fully credentialed teachers (credential based on a bachelor’s degree, teacher preparation program, & student teaching) may substitute for more than 30 days for any one teacher as long as he/she is serving in the subject area(s) authorized by their credential. Fully credentialed teachers may not substitute outside the authorized area for more than 30 days for any one teacher.
T5 §80025: The Emergency 30-Day Substitute Teaching Permit authorizes the holder to serve as a substitute in any classroom; preschool, kindergarten and grades 1-12, inclusive; or in classes organized primarily for adults within each county in which the permit is registered provided the employing agency has a completed Statement of Need on file for the school year. However, the holder shall not serve as a substitute for more than 30 days for any one teacher during the school year.
Title 5 §80025.4: Substituting in a Special Education Classroom: EC §56061(a), which is under the authority of the CDE, specifies that individuals who hold documents authorizing substitute teaching may not serve in a special education classroom for any one teacher more than 20 days during a school year. In order for the teacher to serve in that assignment beyond the 20 day limit, the individual must hold a special education teaching credential, teaching permit, or waiver which authorizes service to the population of students in the classroom.
Sub Rate Sheet / Registering with the Districts (Employers)
You will receive a confirmation email once you are activated on the county-wide sub list. The next step is to register with the district(s), the employers, you want to sub for during the school year.
Questions regarding pay should be directed to your employing district(s).
If at any time you're deactivated from the county-wide sub list, you must reactivate on the county-wide sub list and re-register with your employing district(s).
Should you have any further questions, please connect with your employing school district(s).
Upcoming / New School Year
The school year is July 1st to June 30th.
Active subs who hold a valid, non-expired credential or sub permit and valid TB clearance will remain active on the county-wide sub list and be considered registered and active in the new school year.
If one's credential/sub permit or TB clearance expires on July 1st and the individual lets their credential or TB clearance lapse, the individual is deactivated from the county-wide substitute list. To reactivate, one must complete the reactivation requirements and submit an EdJoin application.
We will continue to provide credential and TB expiration reports at the beginning of each month.
The Keenan trainings will be available and listed in your Keenan profile on Monday, August 4th. The training(s) must be completed by end of day on Friday, September 26th to remain active on the county-wide substitute list. We ask you do not complete the trainings early. If a training is completed early, it will not count towards the 2025/2026 school year requirement.
If one completes the training(s) through a district Keenan account and not through their sub consortium Keenan account, it is the individual's responsibility to mail or deliver the completion certificate(s) to the Marin County Office of Education. We are not accepting emailed certificates.
Failure to complete the training(s) will result in one being deactivated from the county-wide list. Review the information in the "How to Become a Sub" tab to reactivate on the county-wide substitute list.
As in previous years, we will offer watch parties at the MCOE office for those interested. The watch party schedule will be released in late July/early August.
It is your responsibility to connect with your employing school district(s) to inform them of your interest in working in their district.
Keenan Training Information
The County-Wide Substitute Consortium uses Keenan SafeSchools to complete the required trainings.
The required trainings for the 2025/2026 School Year will be announced shortly. The Keenan trainings will be available and listed in your Keenan profile on Monday, August 4th. The training(s) must be completed by end of day on Friday, September 26th to remain active on the county-wide substitute list. We can access your completion certificates, and we ask you do not complete the trainings early. If a training is completed early, it will not count towards the 2025/2026 school year requirement.
The trainings are based on school year (July - June), not calendar year (January - December).
Each district manages it's own Keenan system. Important note: if you complete the trainings through a district Keenan website, or another county office, you must mail, not email, the completion certificates to the Credentials Analyst, as the county will not receive your completion certificates. Upon receiving the certificate(s), we will review for transferability. Additionally, the districts may require additional training(s) that the county does not require subs to complete.
This is the link to the county-wide sub consortium Keenan website. The trainings can be accessed in the "How to Become a Sub" section or by clicking on this link. We ask that your username is your full email address, we do not require you to create a password, and the trainings are automatically assigned.
Expiration Notices
TB and Credential or Sub Permit reminders are emailed from the Credentials Analyst approximately a month prior to expiration.
We encourage you to keep a copy of your TB clearance on file, as we are unable to provide a copy.
TB Clearance:
Your updated TB clearance is due at the end of the month prior to your TB clearance expiring. For example, if your TB clearance expires on April 1st, the updated TB clearance is due no later than March 31st.
I send an email a month prior to expiration. This email includes the TB due date and ways to submit the TB clearance. Emailed documents are not accepted.
It is each sub's responsibility to keep a copy of their TB clearance for their records.
Credential / Sub Permit:
To check the expiration date of your credential or sub permit:
- Visit the Commission on Teacher Credentialing website

TB Clearance
Education Code 49406 and Health and Safety Code § 121525 requires public school employees to be free of infectious tuberculosis (TB). TB clearance is due upon registering on the county-wide substitute list, reactivating on the county-wide substitute list, or every four years.
We encourage you to keep a copy of your TB clearance, as we are unable to provide a copy. Your TB clearance expires four years from the first of the month that you obtained the clearance. For example, if your TB clearance expires on April 1st, the updated TB clearance is due no later than March 31st.
The Credentials Analyst sends a reminder email about a month in advance, but we also recommend adding a reminder to your calendar upon receiving your TB clearance from your healthcare provider.
The updated TB clearance can be mailed or dropped off at the office. For security reasons, we do not accept emailed documents.
Renewing One's Credential or Sub Permit
Clear credentials are valid for 5 years and Emergency 30-Day Substitute Teaching permits are valid for 1 year. The Commission on Teacher Credentialing emails three reminders to you. The Credentials Analyst emails a reminder approximately a month prior to your document expiring.
To check the expiration date of your credential or sub permit:
- Visit the Commission on Teacher Credentialing website
- Click on “Search for an Educator”
- Click on “Secured Search”
- Type your social security number (format: xxxxxxxxx) and date of birth (format: xx/xx/xxxx) then click on the word “Search”.

One is able to renew their document up to 364 days in advance of their document expiring. To renew your document, you will need to log into your account. To login and view a refresher on how to renew, visit the Renew Your Document page on the Commission on Teacher Credentialing's website.
The cost is $102.65, and the Commission on Teacher Credentialing accepts Visa, Mastercard, AMEX, or Discover. Once your application is submitted, your renewal will be granted within 14 business days. After the credential/permit is granted, you will receive an email from the Commission on Teacher Credentialing.
If you're experiencing difficulty logging into your account, please visit the Commission on Teacher Credentialing's help page.
CTC Help Page
The Commission on Teacher Credentialing (CTC) offers a variety of resources:
- The Educator Account Help Page on their website offers assistance with creating your account, updating your information, document help, and application status.
- They also offer a frequently asked questions section located at this link.
- CTC may be contacted via this web form.
AESOP Reminder Emails
The AESOP (or Frontline) administrator is located at your employing district.
Frontline may send you reminder emails about your sub permit or credential expiring. Additionally, some districts may set your credential or sub permit expiration date to June 30th, when the credential or sub permit expires after this date, as June 30th is the last day of the school year.
It is your responsibility to connect with your employing school district to have them update your information. District contact information is available in the "Sub Rate Sheet / Registering with the Districts (Employers)" tab.
Frontline Info + Frontline Assistance
Frontline is used by a variety of districts within the county. If you register with a district that utilizes Frontline, you will receive a welcome document by email or mail. This document includes your pin number, which you'll need to provide if accepting a sub job through the automated calling system.
Immediately after the district creates your profile in Frontline, you should receive an email on how to create your online account. The link expires within the hour, so it's imperative to create your account as soon as possible.
Frontline is available on your desktop browser (Chrome or Edge) or as a free app. We recommend using the free app and make sure your cell phone settings are configured to receive notifications.
