Many families are familiar with the STAR Assessments as a tool for tracking student progress in the classroom. In 2023, the test received a significant update with new norms and now also plays a key role as an admissions exam for some private schools in the U.S.
The STAR assessment is a computerized test that quickly measures a student’s reading, math, and early literacy skills. It’s an adaptive test, meaning the difficulty of each question adjusts based on how the student answers the previous one, providing a highly accurate snapshot of their current academic level. Educators use STAR to track student growth throughout the school year, pinpoint specific areas where they may need help, and guide instruction.
Unlike a traditional test with a fixed set of questions, the STAR assessment adjusts in real time based on your child’s responses. It zeros in on their specific learning level for both Reading and Math, providing a much more accurate picture than a standard test.
If your child answers a question correctly, the test automatically provides a more challenging question next. If they answer incorrectly, the test presents an easier question. This adaptive technology quickly pinpoints your child’s specific academic level, providing an accurate and efficient measure of their abilities. This focused approach saves time and yields precise results that educators can use to create personalized learning plans.
Schools use the STAR Assessment because it provides clear data for student placement and progress monitoring. The scores are a crucial tool for putting students in the right classes and learning groups, ensuring your child feels challenged without being overwhelmed. Teachers also use these scores throughout the year to track progress. This lets them see what’s working and tailor their instruction to each student’s needs. Ultimately, the goal is to foster growth and help every child succeed.
If you’re looking at private schools in the Bay Area, you’ll likely come across the STAR Assessment as a part of the admissions process. Notably, schools like Menlo School in Atherton and Woodside Priory School in Portola Valley have incorporated it into their applications. While other schools in the area may also use it, these two are prominent examples. For these competitive schools, the STAR test provides a standardized way to gauge an applicant’s academic readiness, helping them build a well-rounded incoming class.
Several Bay Area private schools—including Castilleja and Kehillah in Palo Alto, Harker in San Jose, Pinewood in Los Altos, Drew and Nueva in San Francisco, Branson in Marin County, Marin Academy in San Rafael, and others—have used STAR test scores as part of their admissions process or academic evaluation in recent years. Since school policies can change from year to year, it’s important for families to review each school’s current requirements before applying.

The STAR Assessments are flexible and can usually be administered internationally, so your child does not need to fly to the U.S. to take them. STAR tests are computer-adaptive, meaning they adjust in difficulty based on your child’s answers, and they are designed for use in schools, hybrid learning, or even remote setups. If you are living abroad, such as in Luxembourg, the main factor is not location but whether the school or institution requiring the scores accepts remotely administered or internationally proctored STAR exams. Many schools do, but it is always wise to confirm their policies before scheduling.
If your child is taking the STAR test outside of a U.S. school, you will need to make sure the testing setup meets specific requirements. A compatible device, a stable internet connection, and a supported browser are essential to ensure the test runs smoothly. Some schools may ask for a parent, teacher, or professional proctor to supervise the exam to guarantee fairness and prevent outside assistance. Others may require online proctoring software. The goal is to create a controlled testing environment that mirrors what would happen in a classroom setting, so the results are valid and accepted by the requesting institution.
Acceptance policies vary depending on the school or program. Some U.S. schools are very open to STAR scores completed abroad, provided they were administered under the correct conditions, while others may require tests to be taken at an approved location or through a certified proctor. The best approach is to contact the admissions office or academic department directly and ask whether STAR results from an international or remote setting will be accepted. By clarifying early, you avoid complications later and can make sure that your child’s scores are recognized and valued as part of their academic profile.
In many cases, international schools and learning centers already use the STAR Assessments as part of their academic programs, and Luxembourg is no exception. While not every center may advertise STAR testing openly, some international or bilingual schools may already partner with Renaissance, the company behind the STAR Assessments. If the institution your child is applying to requires proctored results, it may be worth reaching out to local schools or contacting Renaissance directly to ask about authorized testing centers in Luxembourg. This option can provide peace of mind by ensuring your child’s scores are administered and validated in a formal environment.
