IHSS assessment procedures and Functional Index criteria are governed by the California Department of Social Services (CDSS). This article reflects publicly available CDSS policy information as of July 2026. Your individual assessment is conducted by a county social worker and results may differ from the general framework described here.
The IHSS Functional Index is a standardized scoring system used by California county social workers to assess how much assistance an IHSS recipient needs with specific daily tasks. Each task — such as bathing, dressing, meal preparation, ambulation, and domestic services — is rated on a scale from 1 (independent) to 5 (requires full assistance). The scores across all assessed tasks directly influence the number of IHSS hours authorized: recipients with higher functional need scores receive more authorized hours, while those with lower scores who can perform many tasks independently receive fewer hours.
Understanding the Functional Index helps recipients and their providers prepare for social worker visits, understand why their current hours are set at a particular level, and recognize when a reassessment may be appropriate if a recipient’s functional ability has declined.
What Is the IHSS Functional Index?
The Functional Index is the structured assessment framework CDSS uses to evaluate how independently a recipient can perform activities of daily living (ADLs) and instrumental activities of daily living (IADLs). It was developed to create a consistent, statewide standard for determining IHSS hour allocations rather than leaving all decisions to individual social worker discretion.
The core principle: The IHSS program is designed to provide assistance with tasks that a recipient cannot safely perform independently due to their disability or medical condition. The Functional Index assesses each relevant task and determines what level of assistance is needed — from cuing and verbal guidance to hands-on physical assistance.
Who is assessed: Every IHSS recipient undergoes a Functional Index assessment during their initial application and during subsequent annual or triggered reassessments. A social worker conducts the assessment in person, typically at the recipient’s home.
The Seven Functional Index Domains and Their Tasks
The IHSS Functional Index evaluates tasks across seven broad service domains:
1. Domestic Services Tasks assessed: housecleaning, laundry, shopping and errands, meal preparation and cleanup, and other related household tasks. The social worker assesses whether the recipient can perform each task independently, with verbal cueing, with minimal assistance, with major assistance, or not at all.
2. Personal Care Services Tasks assessed: bathing, oral hygiene, grooming, dressing, bowel and bladder care (including catheter and colostomy care where applicable), and related personal hygiene tasks. Personal care tasks typically carry higher weight in the overall assessment because of their safety implications.
3. Accompaniment to Medical Appointments Whether the recipient can independently travel to and attend medical, dental, or therapy appointments, or requires provider accompaniment for safety or navigation assistance.
4. Protective Supervision Assessed separately for recipients with cognitive impairments, behavioral conditions, or mental health diagnoses that place them at risk of harm when left unsupervised. Protective supervision hours are authorized based on demonstrated risk, not functional ability alone.
5. Paramedical Services Tasks requiring a medical-level intervention but which a trained non-licensed provider can perform: administering medications, catheter care, feeding tube care, wound care, and similar tasks. Authorized hours for paramedical services require physician documentation.
6. Teaching and Demonstration For recipients who may benefit from learning to perform certain tasks more independently, a limited period of teaching and demonstration hours may be authorized.
7. Respiratory Services Specifically for recipients who require ventilator or respiratory equipment management as part of their care.
The Functional Index Ranking Scale: 1 Through 5
For each assessed task, the social worker assigns a ranking based on the recipient’s demonstrated or documented ability:
| Rank | Description | IHSS Hours Implication |
|---|---|---|
| 1 | Independent — performs task without any assistance | No IHSS hours authorized for this task |
| 2 | Needs verbal cueing, supervision, or standby assistance | Limited hours authorized |
| 3 | Needs minimal hands-on assistance (less than half the task) | Moderate hours authorized |
| 4 | Needs major hands-on assistance (more than half the task) | Significant hours authorized |
| 5 | Cannot perform task at all — requires full assistance | Maximum hours for this task |
The hours authorized for each task are derived from time studies — CDSS research that determined how long each task takes for a provider to perform at each level of assistance. The total monthly hours is the sum of hours across all authorized tasks.
How the Functional Index Translates to IHSS Hours
Each IHSS task has a time-study value: a standardized number of minutes per day (or per week, for less frequent tasks) that a provider needs to complete the task for a recipient at each ranking level.
Example calculation (simplified):
- Bathing, rank 5 (full assistance): Approximately 10-15 minutes per day → roughly 5 hours/month
- Dressing, rank 4 (major assistance): Approximately 8-10 minutes per day → roughly 4 hours/month
- Meal preparation, rank 3 (minimal assistance): Approximately 15 minutes per day → roughly 7.5 hours/month
- Housecleaning, rank 4: Approximately 2 hours/week → roughly 8-9 hours/month
These values are added across all authorized tasks to produce the total monthly authorized hours. The resulting total is what appears in the recipient’s Notice of Action, and what the IHSS provider is paid to provide each month.
Maximum hours: California law caps IHSS hours at a monthly maximum (currently 283 hours per month for most recipients, with exceptions for recipients with exceptional needs). Recipients with the highest functional need scores who qualify for the maximum are said to be on the “cap.”
Preparing for a Functional Index Assessment
Preparation significantly affects assessment outcomes — not by inflating the recipient’s needs, but by ensuring the social worker has accurate, complete information.
What to prepare before the visit:
-
Medical documentation: Gather recent physician notes, diagnoses, treatment plans, and any assessments from therapists or specialists that speak to the recipient’s functional limitations. Written documentation from treating providers carries significant weight.
-
Document the worst-case day, not the best day: Recipients often feel pressure to demonstrate capability during assessment visits. However, the assessment should reflect the recipient’s typical functional capacity, including on days when pain, fatigue, symptoms, or medication effects are worse. If the recipient has good days and bad days, communicate this variation explicitly.
-
List all tasks requiring assistance: Go through each IHSS service domain ahead of time and note which tasks the recipient cannot perform safely or independently. Include tasks that have changed since the last assessment.
-
Have the provider or family member present if possible: A person who regularly assists the recipient can speak to what they actually observe during daily care, which provides corroborating information for the social worker’s assessment.
-
Ask the social worker to explain each ranking as it is assigned: You are entitled to understand how tasks are being scored. If a ranking seems too low based on your actual experience, note your concern during the visit.
What Happens After the Assessment
After the social worker completes the Functional Index assessment, the county generates a Notice of Action (NOA) showing the authorized hours for each task and the total monthly IHSS hours approved.
If you disagree with the assessment results:
- You have 90 days from the date of the NOA to request a State Hearing (also called a fair hearing) to appeal the authorized hours.
- Common grounds for appeal: the functional need is more significant than the assessment captured, a specific task was not assessed or was ranked too low, or a new medical condition was not properly considered.
- Gather additional medical documentation supporting the higher level of need. Physician letters and therapist assessments are particularly persuasive in hearings.
Frequently Asked Questions
Q: Can a recipient’s IHSS hours decrease after an assessment? A: Yes. If a recipient’s functional ability has improved since the last assessment — due to recovery, adaptive equipment, new medications, or other factors — their authorized hours may be reduced to reflect the lower level of need. Recipients may also see hours reduced if a task is reassessed differently by a new social worker. If you believe a reduction is inaccurate, request a State Hearing within 90 days of the NOA to appeal.
Q: Does the Functional Index capture every type of need, including mental health and behavioral needs? A: The Functional Index primarily captures physical functional limitations. Mental health diagnoses, cognitive impairments, and behavioral conditions are addressed partially through the Functional Index (for tasks like grooming and domestic services where cognition affects independence) and separately through protective supervision, which has its own assessment criteria. If a recipient’s primary need is behavioral or cognitive safety supervision rather than physical assistance, protective supervision is the relevant service category to discuss with the social worker.
Q: How often is the Functional Index reassessed? A: IHSS recipients undergo a reassessment at least annually. A reassessment can also be triggered if the recipient’s condition changes significantly — either improving or worsening — or if the recipient moves counties. Recipients can also request a reassessment if they believe their current hours no longer reflect their actual functional needs due to a new diagnosis or a change in condition.
