To become a substitute teacher in Connecticut, you need a bachelor’s degree from a regionally accredited college, a clean fingerprint-based criminal background check, clearance through the Department of Children and Families Central Registry, and a district willing to hire you. No state teaching certificate is required for daily substitute work. If you don’t hold a bachelor’s degree, a district can sponsor a waiver that lets you substitute in that district for one school year at a time.1Justia Law. Connecticut Code Title 10 – Chapter 166 – Section 10-145
Qualify Educationally
The standard path is a bachelor’s degree from a regionally accredited institution. That alone meets the state education requirement for daily substitute positions, and you do not need a teaching certificate on top of it.2CT.gov. What Are the Requirements for Hiring Substitute Teachers For short-term assignments under 40 days in the same classroom, no separate state authorization is needed. The district hires you directly once your background checks come back clean.3Connecticut eRegulations. Section 10-145d-420 Substitute Teacher Authorization
Without a bachelor’s degree, you can still substitute, but only if a specific district wants to hire you and submits a waiver application on your behalf to the Connecticut State Department of Education. The waiver uses Form ED 174, which a superintendent or designated official signs to confirm the district has a staffing need and considers you qualified based on your experience with school-age children.4Connecticut State Department of Education. Application for Substitute Teacher Authorization for Candidates Who Have Not Completed a Bachelors Degree (ED 174) The waiver only covers you in the district that applied, and it expires on June 30. A new application has to go in each school year you want to continue.2CT.gov. What Are the Requirements for Hiring Substitute Teachers You cannot file this yourself. You need the district relationship first.
Clear the Background Checks
Every Connecticut school employee, substitutes included, must pass a national criminal history record check before starting work. It is a fingerprint-based search run through both the State Police Bureau of Identification and the FBI.5Justia Law. Connecticut Code Title 10 – Chapter 170 – Section 10-221d You can get fingerprinted at a state police location, a regional education service center, a local police department, or a private fingerprinting company.
Costs are modest. The state criminal history search fee for public school district employees under C.G.S. 10-221d is $13.25, and fingerprinting at a state police location runs about $15. State fees generally are not charged to governmental employees fingerprinted under a state statute. Regional education service centers and private fingerprinting companies set their own fees, which can push the total higher.6CT.gov. State Police Guide to Processing Fees
Separately, the district runs a search of the Department of Children and Families Central Registry, which lists individuals with substantiated reports of child abuse or neglect. The district initiates the check using DCF Form 3031. The result discloses whether your name appears on the registry.7CT.gov. Background Checks If your name does appear, the hiring district is required to inform you, and you may have the right to contest the finding through the DCF administrative process.8CT.gov.

Apply to a District
Apply directly to the district where you want to work. Most Connecticut districts collect application materials through online platforms, where you upload official transcripts, background check confirmations, and any waiver documentation. Processing takes a few weeks, longer in late summer when districts are onboarding a wave of new staff.
Have your college send official transcripts straight to the hiring district. Electronic delivery is usually faster than paper and carries a small fee at most universities. Districts will not move your application forward without verified academic records, so get this started early.
If your application leads to an interview and an offer, the offer is usually contingent on final board of education approval. You then complete standard employment paperwork, including Form I-9 to verify work eligibility and Form W-4 for federal tax withholding.9Internal Revenue Service.

Complete Mandated Reporter Training
Before you set foot in a classroom, you’ll attend a district orientation covering local protocols, emergency procedures, and the technology the district uses to manage daily assignments. That orientation also addresses your legal duty as a mandated reporter.
All Connecticut school employees are mandated reporters, meaning you are legally required to report suspected child abuse or neglect. New employees have to complete mandated reporter training within six months of being hired, with refresher training every three years after that.10CT.gov. Mandated Reporter Training The Department of Children and Families offers free online training for school employees. Failing to report when you have reasonable cause to suspect abuse carries legal consequences.
Know the Day Limits That Change Your Status
Connecticut tracks how many days you spend in the same assignment, and two thresholds change what’s required.
40 Days in the Same Assignment
Once you’ve been in the same assignment for 40 or more school days in a single year, state regulations require a formal substitute authorization from the Department of Education. The exception is if you already hold a valid Connecticut teaching certificate or certificate of eligibility covering the subject and grade. For non-degreed substitutes working in subject areas that don’t require a bachelor’s degree, the district must get special approval from the Department before you continue past 40 days.3Connecticut eRegulations. Section 10-145d-420 Substitute Teacher Authorization
60 Days as a Long-Term Substitute
Past 60 days in the same position during one school year, the state classifies you as a long-term substitute. The credential bar goes up: a bachelor’s degree plus at least 12 semester hours of college credit in the subject you’re teaching. The district files Form ED 175 along with official transcripts and a letter describing its efforts to recruit a permanent hire.2CT.gov. What Are the Requirements for Hiring Substitute Teachers Long-term authorizations also expire June 30.
What You’ll Earn
Pay is set by each district and varies. Daily rates generally fall between roughly $125 and $200 for short-term assignments, with certified substitutes and long-term placements earning toward the higher end. Retired teachers coming back as substitutes sometimes receive a premium. Districts in higher cost-of-living areas or facing acute shortages sometimes offer bonuses or raised base rates.
Substitutes are typically classified as district employees, not independent contractors, so the district withholds income taxes and may withhold Social Security and Medicare taxes. Social Security coverage for public school employees gets complicated. Connecticut’s Section 218 Agreement with the Social Security Administration can exclude part-time positions, and substitute teaching is generally classified as part-time regardless of how many hours you work in a given week.11Social Security Administration. Part-time Positions If you’re excluded under the agreement and aren’t covered by the state’s public retirement system, mandatory Social Security coverage may still apply. Ask your district’s payroll office during onboarding rather than assuming.
Unemployment During School Breaks
Connecticut’s Department of Labor applies a disqualification to educational employees during scheduled breaks between school years, between semesters, and during holidays, vacations, or recess periods. If you had reasonable assurance of returning to work the following term, you generally won’t qualify for full benefits during those gaps. You might receive a reduced benefit rate during disqualifying periods and the full rate at other times. When you file a claim during one of these periods, you’re required to report that you are an educational employee.12CT.gov. Can I Receive Unemployment if I Am a Teacher or Educational Employee
“Reasonable assurance” is the key phrase. If a district has told you, even informally, that they expect you back next year, that counts. If you have no such assurance and weren’t offered continued work, your eligibility picture looks different. File honestly and disclose your educational employment status up front to avoid clawback problems later.
