What does Alta Regional do?
Alta Regional’s full name is Alta California Regional Center, or ACRC. It decides who qualifies and assigns every client a service coordinator. It pays for services in the IPP, your family member’s plan, after insurance and other help have been tried. The written approval has to be in place before a service starts.
- Adaptive skills trainingAlta’s family guide says it builds self-reliance in daily life: self-care, talking, chores and safety. Parents take part, after a group parent class.
- RespiteSomeone watches your family member so you get a break. Alta gives up to 48, 90 or 120 hours every 3 months, and unused hours don’t carry over.
- Behavior servicesShort-term help with behavior that puts health or safety at risk. For a child with autism, Alta first needs a denial from insurance or Medi-Cal.
- Camp, social activities and lessonsUnder Alta’s May 2026 rule, you don’t have to use up IHSS or trade respite hours to get them.
- DiapersMedi-Cal pays after age 5, and sometimes from 3 with a medical need. Alta can help when those sources fall short.
- Independent living skillsTraining for adults, at home or out in town, to live on their own or do more at home.
- Day programsTraining and community programs for adults.
- Travel trainingLearning to ride the bus or train. Rides to school are the school district’s job.
Other help comes first. Alta must try insurance, Medi-Cal and family supports before it pays, and it pays only for what’s in the plan.

It has to start before age 18 and seriously limit daily life. A child who is 3 or 4 can qualify for now with big limits in 2 areas of daily life.

Early Start is for babies and toddlers with a 25% delay, or with a condition that puts them at high risk. Anyone can refer a child, including a doctor. Alta has 45 days to decide.
What to have ready

Alta’s intake booklet asks for these. A recent, detailed report may mean less testing.

- Alta calls you.Within 15 working days, an Intake Coordinator calls to learn more. Then an Intake Specialist meets with you.
- Alta decides.A team with a doctor, a psychologist and a social worker decides within 120 days. If your family member qualifies, a service coordinator reaches out within 60 days.
From age 3 up, the person or their family opens the My Alta account. Alta doesn’t take referrals from other agencies at that age. More on who qualifies: our eligibility page.
Alta questions, answered
Is Alta Regional Center free?
Yes, to find out if you qualify. Alta’s testing is free, and so is writing the plan, the IPP, if your family member qualifies. Then Alta pays for the services in the plan, once insurance and other help have been tried.
Does Alta Regional help with housing?
It can help an adult get ready to live on their own. Alta pays for independent living services. They teach what it takes to move into a home of their own, or to do more for themselves at home. Alta also has a Housing Specialist who works on housing in its area. Ask your coordinator what’s open to your family member.
What counties does Alta serve?
Alta serves Sacramento, Placer, Yolo, El Dorado and Nevada counties. It also covers Sutter, Yuba, Colusa, Sierra and Alpine. San Joaquin County belongs to Valley Mountain Regional Center, Butte and Glenn to Far Northern, and Napa and Solano to North Bay. Near a county line? Check your ZIP code.
How much respite can Alta give?
Up to 120 hours every 3 months. Your planning team picks a level of up to 48, 90 or 120 hours. Hours you don’t use in a quarter are lost, and two quarters with no use can end the service. More than 120 takes an exception from Alta’s Family Services and Supports Committee.
Would adaptive skills training through Alta lower our IHSS or respite hours?
No. Alta adding this won’t trim your hours of IHSS or respite. All counties got a letter from the state. It says to plan IHSS as if Alta did nothing for you. The letter is short.
What is the Alta Regional portal?
It’s My Alta, where you apply online. Once you make an account, you log in to apply and to see where your application stands. To reach a coordinator, use Alta’s staff directory instead.
Is there an age limit at Alta?
No. Alta serves people of all ages, for life. Adults can apply too, as long as the disability began before age 18.
Can Alta diagnose autism?
Yes, during intake. Alta provides or pays for the testing needed to see if your family member qualifies, including a psychologist’s exam to confirm autism. It’s free.
What is the Alta medical waiver?
It’s the Medicaid Waiver, also called the HCBS Waiver. It lets the county skip your family’s income when your child applies for Medi-Cal. Alta’s guide says Medi-Cal can then cover diapers, supplies and often co-pays. Your coordinator can sign your child up, and joining is your choice.
How do I reach my Alta service coordinator?
Alta posts its whole staff directory, plus a three-step plan for when you can’t get through. Here’s how to use both.
- Look them up.Search Alta’s staff directory by name for a direct phone number, or send a message from it. The message form doesn’t send you a copy, so keep your own.
- No promised call-back time.Alta’s site doesn’t say how fast coordinators answer. If you don’t hear back, go to step 2 below.
- No officer of the day.Families search for Alta’s officer of the day, but Alta doesn’t name one. Its reception desk, (916) 978-6400, will connect you with the person you need.
- Step 2: the Client Services Manager.Alta says to call your coordinator first, then their manager. The manager’s name and phone are at the bottom of your coordinator’s emails. Step 3 is a Director of Client Services; their numbers are on the staff directory page.
- Keep a log.The state’s guide on Alta’s site says to write down the day you called, who you talked to and what they said. Note voicemails and emails too.
- New coordinator?Alta’s coordinators work by age group, so a child usually gets a new one at 3 and again at 17. Alta says the old and new coordinators work together when they can. If yours isn’t a good fit, you can ask for someone else.
How do I get adaptive skills training through Alta?
Talk to your service coordinator. Alta says families can ask for new or different services whenever the need comes up.
- Email your coordinator.Say you want adaptive skills training from Aldera, and copy team@aldera.org. Start from this email. List the everyday skills that are hardest now.
- Take the parent class.Alta’s family guide asks parents to join a group class, Behavior Parent Training, first. Ask your coordinator to sign you up.
- A meeting within 30 days.The state’s guide on Alta’s site says a planning meeting happens within 30 days of your request. Ask for adaptive skills training to go in the plan.
- Sign, then we start.Services start once you sign the plan. After Alta approves it, we come to your home and set goals with you and your family member.
Alta’s guide calls it a 3 to 6 month service that also coaches parents, so the skills keep growing after it ends.
How do I get a copy of my family member’s Alta records?
Reports from Alta, like the psychological evaluation, can back up an application for IHSS or SSI. The state’s guide on Alta’s site explains how to get them.
- Ask your coordinator in writing.Ask to see the file or to get copies. Say if you want to pick them up, or get them by email or mail.
- 3 business days.Alta has to let you see the file within 3 business days of your request.
- Intake tests count too.Even if your family member didn’t qualify, you can get a copy of any test Alta did. Ask your Intake Specialist.
- Using them for IHSS.IHSS asks for a health form, the SOC 873, from a licensed professional. An IPP with the same facts can count instead. Alta’s family guide adds that a child needs active Medi-Cal before IHSS can help. If you’ll care for your child yourself, see how parents get paid through IHSS.
How do I get school help in Sacramento and Alta’s other counties?
School districts run special education, not Alta. But Alta has an Education Support Team, and your coordinator can refer you to it.
- Write to the school.Ask for a special education assessment in a signed, dated letter or email. Sacramento City Unified points out that email leaves a record.
- A plan within 15 days.The district has 15 days from your request to send you an assessment plan to sign.
- 60 days to test.Once the district has your signed plan, it has 60 days to test and hold the IEP meeting.
- Get Alta’s help.Your coordinator can set up a talk with Alta’s Special Education Specialist, who can go over an IEP with you. Elk Grove’s handbook says you can bring your Regional Center worker to the meeting.
- Plan for preschool early.The state’s guide says the transition meeting with the school comes at least 90 days before your child turns 3.
