October 1, 2026 is 4.5 months away. Connecticut SB 5's automated employment decision technology rules take effect then — and any Connecticut employer using AI in hiring, performance evaluation, or other employment decisions needs to be ready. Here are the 10 steps to complete before the deadline.
What Takes Effect October 1, 2026
Connecticut SB 5 has multiple effective dates. The October 1, 2026 tranche covers:
- AEDT anti-discrimination rules — employers must not use AEDT that has adverse impact on protected classes without business necessity justification
- AEDT developer disclosure obligations — AI tool developers must provide compliance packages to deployers (employers)
- Frontier AI company whistleblower protections — employees of companies training frontier AI models protected for reporting catastrophic risk concerns
The October 1, 2027 tranche covers:
- AEDT deployer disclosure to applicants and employees — employers must notify individuals that AEDT is being used
- Pre-decision notices — individuals receive notice and opportunity to provide supplemental information before an adverse employment decision using AEDT output
- Individual data rights — rights to request information about AEDT decisions
- Synthetic media marking obligations
What this means for your checklist: Steps 1–3 (inventory, developer compliance packages, adverse impact analysis) and Step 7 (whistleblower policy) must be ready by October 1, 2026. Steps 4 and 5 (disclosure language and job posting updates) are required by October 1, 2027 — start building them now so you are not scrambling.
The 10-Step October 2026 Compliance Checklist
Step 1: Inventory Your AEDT Tools
List every AI tool used in employment decisions. A tool qualifies as AEDT if it generates output that is a "substantial factor" in decisions about hiring, promotion, performance evaluation, scheduling, or termination.
Include in your inventory:
- Resume screening and ranking platforms
- Video interview analysis tools
- Assessment or aptitude test tools
- Performance scoring systems
- Work scheduling algorithms (if they affect employment terms)
Exclude: Tools used only for calendar management, payroll processing, or benefits administration with no influence on employment decisions.
Step 2: Request Developer Compliance Packages
For each AEDT tool in your inventory, request from the vendor:
- Bias audit results covering the job categories you use the tool for
- Adverse impact analysis by protected class
- Description of the data used to train or validate the tool
- Technical documentation on how the tool generates its output
- Statement confirming the tool complies with Connecticut SB 5 deployer requirements
Connecticut SB 5 requires AEDT developers to provide this information to deployers. If a vendor cannot produce it, that is a compliance gap requiring escalation.
Step 3: Run Your Own Adverse Impact Analysis
Do not rely on vendor documentation alone. Pull your data and calculate selection rates by protected class for each AEDT tool. Use the EEOC four-fifths rule as your benchmark — see the EEOC AI hiring compliance checklist for the calculation methodology.
Document your findings. If adverse impact exists:
- Investigate whether the tool is serving a genuine business necessity
- Evaluate alternative tools or processes with lower adverse impact
- Consult legal counsel on whether to continue using the tool
Step 4: Draft AEDT Disclosure Language (Required by October 1, 2027 — begin now)
Connecticut SB 5 requires disclosure to applicants and employees that AEDT is being used and what role it plays. This obligation takes effect October 1, 2027, but drafting it now ensures you are not rushing under deadline pressure. Draft language for:
Job application disclosure:
"We use automated employment decision technology [describe tool type] to [screen/rank/evaluate] applications for this role. This technology [briefly describe what it evaluates]. You may contact [contact] to learn more."
Employee notice (before AEDT used in employment decisions):
"We use automated tools that analyze [describe what is analyzed] to inform decisions about [performance evaluation/scheduling/etc.]. These tools are one input in our decision process."
Have legal counsel review the final language before October 1, 2027.
Step 5: Update Your Job Posting Templates (Required by October 1, 2027 — begin now)
Add the AEDT disclosure to your job posting template so it appears automatically on all postings where AI screening is used. This takes effect October 1, 2027 — prepare the template now and hold it for implementation. Also plan updates to:
- Application confirmation emails (if AEDT triggers at application submission)
- Employee handbook section on performance review process
Step 6: Establish an Adverse Decision Notice Procedure
The full pre-decision notice requirement does not apply until October 1, 2027, but you should build the procedure now. When AEDT output is a substantial factor in a negative employment decision (rejection, demotion, termination), the individual must eventually receive notice and an opportunity to provide supplemental information.
Build a procedure:
- Who triggers the notice (HR? Hiring manager?)
- What the notice says (what the AI evaluated, what the outcome was, how to submit supplemental information)
- Timeline for response (how long does the individual have to respond?)
- Who reviews the supplemental information and can override the AEDT output?
Step 7: Add Whistleblower Protection Language to Policies
Connecticut SB 5's formal whistleblower protection (effective October 1, 2026) applies to employees at companies developing frontier AI models (trained with more than 10^26 FLOPs) who report concerns about catastrophic risk. If your company is not a frontier AI developer, this provision does not directly apply — but updating your employment policies to reflect anti-retaliation protections for employees who raise AI governance concerns is best practice regardless. Update your employment policies and handbook to:
- Provide a clear channel for reporting AI concerns (HR, anonymous hotline, or compliance email)
- State that retaliation for raising AI-related concerns in good faith is prohibited
- Reference applicable Connecticut SB 5 obligations if your company trains frontier-scale models
Step 8: Assign a Compliance Owner
Name one person responsible for SB 5 AEDT compliance. Responsibilities include:
- Maintaining the AEDT inventory
- Collecting and filing vendor compliance packages
- Running the quarterly adverse impact analysis
- Responding to employee inquiries about AEDT use
- Handling any AG inquiry within the 60-day cure period
Step 9: Set a Review Calendar
Build recurring calendar events for:
- Quarterly: Pull AEDT selection rate data; recalculate adverse impact by protected class
- Annually (September): Request updated vendor compliance packages before October review
- On tool update: Rerun adverse impact analysis after any vendor model update
Step 10: File a Readiness Assessment by September 15
Two weeks before the October 1 deadline, do a final check:
- AEDT inventory complete
- Developer compliance packages received for all tools
- Adverse impact analysis complete; no unaddressed disparities
- AEDT disclosure language added to job postings and employee notices
- Adverse decision notice procedure documented
- Whistleblower protection language added to policies
- Compliance owner named and notified
Any gaps discovered here need to be remedied before October 1 — or you start October in a curable violation posture (60-day cure window applies).
