Shared campus · © OpenStreetMap

Henderson, Valley Robotics Academy and Independence share this address in the state’s school directory. OpenStreetMap maps the grounds as one campus. Which buildings each school uses here isn’t mapped.

Schools maintain a closed campus policy. For students’ safety, visitors may enter a campus only with the school’s official permission; this drawing implies no permission to enter.

15% of the 20 students tested met or exceeded the standard in English (reading and writing); none did in math. In grade 8, spring 2022, 15% of the 20 students tested met or exceeded the standard in English, against 47% across California. In math, none did, against 29% across California. Fewer than 30 students tested, so one year can swing a lot; ask how results looked in other years.

What you can do

Who can act on Henderson’s results?

Lodi Unified’s board decides Henderson’s plan.

The state hasn’t placed Henderson in a support program. Federal designation under the Every Student Succeeds Act, 2025–26. Source 

What has the state flagged?

The state is giving Lodi Unified extra help in 2026. It qualified on the 2025 California School Dashboard. The county office must help the district for at least three years, including a review of its yearly plan.

How the California mean was selected

SchoolScope starts with its selected California finance records, not every NCES California district. For FY 2020–21, it calculates an unweighted mean of NCES F-33 current expense per pupil. District records contribute once, regardless of enrollment. The calculation keeps records with positive per-pupil current expense, enrollment over 100, CCD agency type 1, and a recorded district name; it excludes names ending in County Office of Education, Department of Education, or Superintendent of Schools. This is a SchoolScope calculation, not a state-published spending average.

These shares are our arithmetic: each group’s dollars divided by the $461,318,621 total of the groups shown, rounded to whole percents by largest remainder so they add up to 100. Dollar amounts are rounded to the nearest dollar, so they can differ from the total by a dollar. SchoolScope groups district-level CDE SACS UserGL actuals from Fund 01, using operating objects 1000–5999 and excluding retiree benefits, food and community services, facilities acquisition, other outgo, and nonagency goals. These shares use that filtered total; they do not exactly break down CDE's official current expense per ADA above. The school-level ESSA figure uses a separate source.
