Planning standardized tests is one of the most important parts of the admissions timeline for both college and private school applicants. Students applying to U.S. colleges often take the SAT or ACT, while those applying to private schools and boarding schools may need the SSAT, ISEE, or HSPT. Because these exams are offered only on specific dates or within certain testing windows, families need to stay organized and plan ahead.
Registration deadlines usually occur several weeks before the exam itself. Missing those deadlines can mean waiting months for the next opportunity. That is why many families map out their testing schedules early in the academic year.
This guide provides an overview of the most common standardized tests used for college admissions and private school admissions. Below you will find the latest SAT, ACT, SSAT, ISEE, and HSPT test dates along with registration deadlines so families can plan accordingly.

2026-2027 SAT Test Dates and Registration Deadlines
The SAT is one of the most widely used standardized tests for college admissions in the United States. It measures students’ readiness for college-level work through sections focused on reading, writing, and mathematics. Because the exam is offered multiple times per year, many students take the SAT more than once to improve their scores.
Registration for the SAT usually closes about four weeks before the exam date. Students who register late may need to pay additional fees and may have fewer available testing locations.

Many students take their first SAT in the spring of junior year and may take additional tests during the summer or fall before submitting college applications.
2026-2027 ACT Test Dates and Registration Deadlines
The ACT is another widely accepted college admissions exam. Like the SAT, it is offered several times throughout the year and is accepted by virtually all U.S. colleges and universities.
The ACT includes sections on English, math, reading, and science reasoning, along with an optional writing component. Some students prefer the ACT because of its faster pacing and slightly different testing format.
ACT registration deadlines typically occur four to five weeks before the exam date. Early registration helps ensure students can test at a convenient location.

Students who plan carefully often take their first ACT during junior year and may take it again later to strengthen their scores.
2026 SSAT Test Dates and Registration Deadlines
The Secondary School Admission Test (SSAT) is commonly required for students applying to competitive private schools and boarding schools. The exam measures verbal, quantitative, and reading skills and is available at multiple levels depending on a student’s grade. The test is offered in three formats: the standard pen-and-paper SSAT, the SSAT at Home, and Prometric.
The SSAT is typically offered during the fall and winter months when private school admissions applications are due. Because many schools set application deadlines between December and January, students often take the SSAT earlier in the testing season to ensure their scores arrive on time.
As of March 2026, registration for the standard pen-and-paper testing is closed and will reopen on August 1.

Prometric Centers are available in the United States, Canada, and most countries. Visit here to find the center nearest you. On the drop-down, select “SSAT by The Enrollment Management Association” as the test sponsor.
Students applying to selective boarding schools may take the SSAT more than once to strengthen their scores before application deadlines.
2026 ISEE Test Dates and Testing Windows
The Independent School Entrance Exam (ISEE) is another test used by private schools across the United States. Unlike the SAT or ACT, the ISEE is offered in testing windows rather than fixed national test dates.
These windows typically include:
- Fall testing window
- Winter testing window
- Spring testing window
- Summer testing window
Students may test once during each window depending on the testing format they choose. Because of this flexibility, families often schedule ISEE exams several months before admissions deadlines to allow time for additional attempts if necessary.
HSPT Test Dates and Registration Information
The High School Placement Test (HSPT) is used by many Catholic high schools as part of their admissions process. Unlike national exams such as the SAT or ACT, the HSPT is administered directly by individual schools or dioceses.
Because each school manages its own testing schedule, the exam is usually offered only once per year. Most Catholic high schools administer the HSPT during the fall or early winter before admissions decisions are released.
Families applying to Catholic schools should check directly with the schools on their list to confirm specific HSPT testing dates and registration requirements.
How Families Should Plan Test Dates for Admissions
Planning standardized tests well in advance helps students reduce stress and perform at their best. Families should consider admissions deadlines, school calendars, and preparation timelines when scheduling exams.
For college admissions, many students begin testing during junior year. Taking the SAT or ACT in the spring allows students time to retake the exam later if needed.
For private school admissions, testing typically happens earlier. Students applying to boarding schools often take the SSAT or ISEE during the fall before applications are due.
Starting preparation several months before the first official test date gives students time to strengthen skills, build confidence, and improve scores through practice.
Typical Testing Timeline for High School Students
Sophomore Year
Some students begin exploring standardized tests and may take diagnostic exams to identify strengths and weaknesses.
Spring of Junior Year
Students often take their first SAT or ACT.
Summer Before Senior Year
Many students continue preparation and schedule additional testing if they want to improve their scores.
Fall of Senior Year
Final SAT or ACT attempts are often completed before college applications are submitted.
Typical Testing Timeline for Private School and Boarding School Applicants
For private school and boarding school applicants, students usually take the SSAT or ISEE during the fall before admissions deadlines.
Planning Your Testing Strategy
Standardized testing is only one part of the admissions process, but choosing the right testing timeline can make a significant difference. With proper planning, students can schedule exams strategically and leave enough time to improve their scores if necessary.
Families who want additional guidance often work with experienced admissions consultants and test preparation specialists to create a clear testing plan that aligns with their academic goals and application timelines.
