Our Child Turns 4 Next Year and We're Buying in Palo Alto — Can They Start TK at the Elementary School Down the Street?

Direct answer

Not necessarily. Only 6 of Palo Alto Unified's 12 elementary schools offer TK. Children are placed at a TK campus in their neighborhood school's cluster, space permitting, and return to the neighborhood school for kindergarten. A child is eligible once they turn four on or before September 1.

Who this article is for

• Families whose child turns four between September 2, 2026 and September 1, 2027 (born September 2, 2022 through September 1, 2023), touring Palo Alto school-district single-family homes at $5 million and up, who want to know where that first school year will happen before they write an offer
• Buyers who have settled on PAUSD and are weighing addresses across several elementary attendance areas, and want to know which campus their child will be assigned to for TK and how far the daily drop-off will run
• Families also looking at Menlo Park, Atherton, Los Altos, Cupertino, or Hillsborough who want each district's TK sites and placement rules in the comparison — including families relocating from out of state or abroad who need to work closing and move-in dates backward

Three things that actually decide this

"Can my child do TK at the neighborhood school?" is really three questions stacked together: which schools offer TK, when you have to be living in the home, and whether that year has to be public TK at all. Taken one at a time, each has a clear answer on the district websites.

One: where TK is offered — only 6 of PAUSD's 12 elementary schools

PAUSD's TK page puts it in one line: PAUSD has TK classrooms at seven elementary schools: Barron Park, Duveneck, El Carmelo, Fairmeadow, Greendell, Palo Verde, and Walter Hays. Materials from the district's February 2, 2026 TK/K parent information night sort those seven sites into three clusters. North: Addison, Duveneck (+TK), and Walter Hays (+TK). West: Barron Park (+TK), Escondido, Juana Briones, and Nixon. South: El Carmelo (+TK), Fairmeadow (+TK), and Palo Verde (+TK). Greendell, the district's only preschool campus, sits in a column of its own. The same materials count 12 TK-5 elementary schools in PAUSD; Hoover and Ohlone are choice-program schools, and Escondido also houses a Spanish immersion program. Do the arithmetic: 6 of the 12 elementary schools offer TK, and with Greendell the total is 7 sites.

The placement rule is on the same page: PAUSD will place TK students in the school that is in the same cluster as the student's neighborhood elementary school (if space is available)… TK students will be enrolled for Kindergarten in the neighborhood elementary school. The district's School Placement & Transfers page adds a separate line: Transitional kindergarten does not follow the neighborhood school placement process. The chain runs like this. The address sets the neighborhood elementary school. The neighborhood school sets the cluster. Whichever TK campus in that cluster has space is where the child goes, and only at kindergarten does the child return to the neighborhood school. For an address assigned to Addison, Escondido, Juana Briones, or Nixon, the TK year will be spent at a different school, without exception.

Two timing details matter to a buyer. First, PAUSD's priority registration applies only to kindergarten, and TK placements are announced by June. An offer written in spring can confirm the cluster; it cannot confirm the specific TK campus. Second, the list of sites changes from year to year. CDE DataQuest enrollment data show that in 2024-25, PAUSD had TK students at four elementary schools: Barron Park, Duveneck, Fairmeadow, and Walter Hays. In 2025-26, El Carmelo and Palo Verde joined, for six. For 2026-27 the district's list adds Greendell, for seven. The cluster also sets the middle and high school path; how to trace an address all the way to Gunn or Paly is covered in Buying a Palo Alto School-District Home: How Do I Know Whether an Address Feeds Gunn or Paly?

Two: when you have to be living there — the age line moves the calendar up a year

The TK age line is set by state law. Education Code §48000(c)(1)(G) reads: In the 2025–26 school year, and in each school year thereafter, a child who will have their fourth birthday by September 1 shall be admitted to a transitional kindergarten program maintained by the school district or charter school. That is the end point of a four-year expansion that began in 2022-23 and took full effect in 2025-26. In birth dates, PAUSD, Cupertino Union, and Los Altos all publish the same 2026-27 TK window: September 2, 2021 through September 1, 2022, with a September 1 birthday included. By the same statute, the 2027-28 window works out to September 2, 2022 through September 1, 2023. Kindergarten's line is turning five on or before September 1 (subdivision (a) of the same section). Take the family in the title. If the child turns four in 2027 on or before September 1, TK starts in fall 2027. If the birthday falls on September 2 or later, it starts in fall 2028.

TK, like kindergarten, follows where you live, not what you own. PAUSD's registration page states that only current residents may register, and that future residents may register two weeks before their move-in date. Cupertino Union is stricter: a family must already be living full-time at the district address to complete registration, and the district does no pre-registration. PAUSD's boundary is also not the city line. The district notes that some areas of Palo Alto fall outside PAUSD, while some areas of Los Altos Hills and Portola Valley fall inside it. For a family whose child turns four in 2027 on or before September 1, closing and move-in have to aim at the fall 2027 start, not 2028. What proof of residence each district asks for, and how to count backward from the first day of school, we covered in Relocating to the Bay Area for School: When Do You Have to Close and Move In to Make Fall Enrollment? We won't repeat it here.

The market makes that year tighter. MK Bay Area Pulse, the quarterly report MK Group compiles from MLSListings single-family closed-sale data, shows 139 Palo Alto single-family closings in Q2 2026 at a median sale price of $4,100,000, a median of 8 days on market, sale prices at a median 105.6% of original list, and 36.0% all-cash. In Los Altos the median sale price was $4,920,000, again with a median of 8 days on market. When homes go in 8 days and more than a third of the competing buyers are paying cash, the TK question has to be answered while you are still touring, not after the offer.

Three: does that year have to be public TK? No — private preschool is a legitimate bridge

California's compulsory education starts at age six (Education Code §48200). The TK pages of Menlo Park City, Las Lomitas, and Hillsborough all say TK is not required — Menlo Park City and Hillsborough in the words TK is not a mandatory grade, Las Lomitas as TK is not mandatory — and Hillsborough explicitly notes that parents may choose to keep their child in preschool. Public TK's staffing is also fixed by statute: Education Code §48000(g) caps average TK class enrollment at 24 per school site and, from 2025-26, requires at least one adult for every 10 students.

Not required does not mean you can step in and out at will. Las Lomitas states that children who attend TK must continue to kindergarten the following year, and that children whose birthdays fall in the TK window cannot skip to kindergarten. Cupertino Union states that its birth-date windows have no flexibility and that it does not assess TK-age children for placement in kindergarten. State law leaves room for districts to approve early kindergarten entry case by case (§48000(b)), but PAUSD's registration page says it does not allow early admission to kindergarten. So for a child whose birthday falls in the TK window, the public path takes one of two forms: TK followed by kindergarten, two years in all, or no public school that year and kindergarten directly the next.

Palo Alto's enrollment numbers suggest the second route is common. CDE DataQuest shows 203 TK students and 594 kindergartners in PAUSD in 2025-26, so TK ran about one-third of kindergarten; statewide that year it was 213,313 to 355,391, about six in ten. Each grade represents a full year's birth cohort, so by the numbers, a sizable share of age-eligible children in PAUSD attendance areas did not attend public TK that year. If closing lands after school starts, or the assigned TK campus makes the drop-off impractical, giving that year to a private preschool and registering at the neighborhood school for kindergarten is an entirely normal path.

PAUSD's TK campuses by cluster, in one table

The core numbers first. Of PAUSD's seven TK sites for 2026-27, the North cluster has two, the West cluster one, and the South cluster three, with Greendell listed on its own. In 2025-26 the largest TK enrollment was at Walter Hays in the North cluster (55 students), and every TK student from the West cluster's four elementary schools attended Barron Park (36).

Sources: PAUSD February 2026 TK/K information night materials (cluster assignments); PAUSD TK page (TK campus list, Young Fives relocation); CDE DataQuest 2025-26 Census Day enrollment by grade

What to take from this: these are enrollment counts, not seat caps, and they cannot be turned into odds of being shut out. What they show is distribution. The West cluster's four elementary schools enrolled 193 kindergartners in 2025-26 (Escondido's 80 include its districtwide Spanish immersion program), while the cluster's only TK campus, Barron Park, enrolled 36. The North cluster's two TK campuses together enrolled 93, and the South cluster's three enrolled 71. For a West cluster address, the TK-year drop-off is close to settled in advance: Barron Park. For the Addison area in the North cluster, it is Duveneck or Walter Hays, with the district deciding by available space. And the table will keep moving in 2026-27, as Greendell's addition shows.

TK rules across six districts, in one table

The core numbers first. All six districts use the same age line, four on or before September 1, but the number of TK sites varies widely. Las Lomitas has one. Menlo Park City and Hillsborough have three each. All seven Los Altos elementary schools have TK. Cupertino Union offers it at every neighborhood elementary school, with three specialty schools left out. PAUSD has seven sites. In 2025-26, TK enrollment as a share of kindergarten ranged from about 34% in PAUSD to about 84% in Las Lomitas.

Sources: district websites (read October 2026); The Almanac, January 14, 2026 (Menlo Park City and Las Lomitas registration opening dates); CDE DataQuest 2025-26 Census Day enrollment by grade

What to take from this: a guaranteed seat and a guaranteed school are two different promises. Las Lomitas makes both, because the whole district has a single TK campus. Menlo Park City makes only the first. PAUSD makes both conditional on available space. The TK-to-K ratio is not a verdict on any school; it reflects how many age-eligible families use public TK that year — about 34% in PAUSD, about 60% statewide. One more caution: in Atherton and Menlo Park, an address first has to be placed in Menlo Park City, Las Lomitas, or Redwood City School District before any of these TK rules apply. How to check is laid out in Buying in Atherton or Menlo Park — Which School District Do Your Kids Actually Land In? Does Atherton Even Have Its Own Schools?

What MK Group sees in the field

MK Group, founded by Marie Wang (DRE# 02110980) and Kevin Mo (DRE# 02127623), has three published anonymized cases that bear on this. None involves a TK-age child, but together they show the two things underneath the TK question: an address has to be verified street by street, and a school-driven purchase runs on the enrollment calendar.

The first is street-level verification. In one Atherton Oaks buyer's school-boundary review, the issue was that Atherton spans three elementary districts — Las Lomitas, Menlo Park City, and Redwood City — with assignment decided street by street, and the house the client first favored sat on the other side of the line. Before the offer, the team checked the attendance area street by street and compared homes of the same caliber a few blocks away, across the boundary; the client changed course. Per the case record, comparable homes on the two sides of that line trade about $1.5 million apart. PAUSD's TK pushes the same verification one level deeper: the address sets the neighborhood school, the neighborhood school sets the cluster, and the cluster sets the TK campus.

The second is timing. A dual-income couple doing AI research at a major Seattle tech company moved to Palo Alto for their eight-year-old daughter's education and closed in May 2026. What pushed them was the school-choice window as she approached the move from elementary to middle school. Before each trip in, the team prepared remote walkthrough videos and data screening, so that three to five days on the ground went to the best-matched homes. The other is a $5.25 million school-district home in Menlo Park, where the team stayed with the client for five full years, from the first showing to closing. Read together: a school-driven buyer's pace is set by the enrollment window, and the right house does not appear on that schedule. TK moves the window up a year. If your child turns four in 2027 on or before September 1, either you are living in the home before fall 2027 classes begin, or you accept a year of private preschool first.

Common mistakes

Mistake one: "Whatever elementary school our address is assigned to, that's where TK will be"

Not in PAUSD. Only 6 of 12 elementary schools offer TK, 7 sites counting Greendell; for addresses assigned to Addison, Escondido, Juana Briones, or Nixon, the TK year will be spent on another campus. Even when the neighborhood school does offer TK, the district states that TK does not follow the neighborhood school placement process. Children are placed by cluster and available space, and return to the neighborhood school for kindergarten. Other districts have similar rules: Menlo Park City says it does not guarantee TK placement at a specific school, and Las Lomitas has a single TK campus for the whole district.

Mistake two: "TK works like kindergarten — register during priority registration and the school is locked in"

PAUSD states that priority registration applies only to kindergarten; TK placements are announced by June, kindergarten placements by mid-May. Menlo Park City's TK FAQ says there is no priority registration for TK. Hillsborough's two priority groups — siblings of current students, and families who complete registration within the priority window — are both written for K-5 students, with TK campuses announced separately in spring. Registering early still helps, since Los Altos and Hillsborough both use the date registration is completed as one placement factor. For the TK year, though, it does not buy a guarantee of a specific campus.

Mistake three: "Our child is TK age but ready, so they can go straight to kindergarten"

In the districts covered here, generally not. The kindergarten line is turning five on or before September 1 (Education Code §48000(a)). State law lets districts approve early kindergarten entry case by case, but PAUSD says it does not allow early admission to kindergarten. Cupertino Union says its birth-date windows have no flexibility and that it does not assess TK-age children for kindergarten placement. Las Lomitas says children with birthdays in the TK window cannot skip to kindergarten. For a child whose birthday falls in the TK window, the public path is TK and then kindergarten, two years in all, or no public school that year and kindergarten the next.

Mistake four: "TK is optional, so skipping it has no effect on kindergarten"

As schooling, it is optional: California's compulsory education starts at age six (Education Code §48200). On placement, though, children who complete TK have a ready-made transition. Hillsborough holds a kindergarten seat at the resident school with no re-enrollment, Las Lomitas moves TK students up to kindergarten automatically, and PAUSD enrolls TK students for kindergarten at the neighborhood school. A child who skipped public TK registers for kindergarten as a new student. PAUSD's site states that students who complete kindergarten registration during priority registration receive equal priority placement at their neighborhood school; if the neighborhood school is full, a student may be overflowed to another school in the cluster and is automatically waitlisted for the neighborhood school. Los Altos, when full, overflows to another district school with a waitlist. The private preschool route works perfectly well, provided the kindergarten-year priority registration window is not missed.

Next steps

1. Start by matching the birthday to a school year. Children born September 2, 2022 through September 1, 2023 fall in the 2027-28 TK year (calculated from Education Code §48000; districts publish the official window during registration season). Birthdays on September 2, 2023 or later fall in 2028-29. Make that school year the first line of your purchase timeline.
2. Once you have a specific address, look up the neighborhood elementary school in PAUSD's School Finder, then match it against the cluster table in the district's February 2026 information night materials to find the TK campuses in the same cluster, and build the first year's drop-off route into your decision. In other districts, use each district's School Locator; for Atherton and Menlo Park addresses, confirm the district first.
3. Before the offer, email the district registration office for a written answer: which TK campuses this address maps to for the next school year, whether there is space now, and what happens when they are full. PAUSD went from four TK schools in 2024-25 to seven sites in 2026-27 — two changes in three years — so neither a verbal answer nor last year's list is a sound basis.
4. Work closing and move-in backward. Hillsborough's 2027-28 registration opens December 7, 2026; Los Altos' priority window runs January 20 to February 5, 2027; Menlo Park City opens on the first Monday of February each year; PAUSD's last cycle opened December 1, 2025. PAUSD allows registration two weeks before move-in; Cupertino Union requires the family to be living there full-time.
5. Keep a Plan B for the TK year. If closing cannot make the fall 2027 start, or the assigned TK campus makes the drop-off impractical, give that year to a private preschool and put the 2028-29 kindergarten registration window on the calendar now. In Cupertino Union, Open Enrollment approval for TK at a non-neighborhood school covers one school year only, so the following year means facing kindergarten placement all over again.
