Applying to private school? We have over 15 years experience teaching students how to excel on the SSAT and ISEE!

Why You Should Choose Sandweiss Test Prep for Your ISEE & SSAT Prep

Since 1998, Sandweiss Test Prep has been offering comprehensive test preparation services, academic tutoring, and admissions consulting to elementary, middle & high school students throughout the Puget Sound. We are a local company dedicated to providing high-quality instruction, affordable rates, and flexible learning options, all with the goal of helping your child succeed on their ISEE or SSAT.

Our course provides the most comprehensive support you’re likely to find when researching ISEE & SSAT course options. We’ll teach you to tackle every question type in detail, provide you with effective strategies for managing each section, and help you maximize your overall score.

In addition to offering expert test preparation, we can also provide guidance with selecting schools and writing application essays for families seeking admission to local private schools.

For the foreseeable future, we’ll be holding both in-person and online, small group ISEE/SSAT courses.

  • Online courses are held via Zoom with lesson times specified in synchronous time. 
    • Zoom allows for students to ask questions, interact with each other and the teacher, participate verbally and use the virtual whiteboard – without having to deal with traffic to and from our office!  
  • In-person courses are held in our new Seattle office.  Students attending in-person courses are required to comply with all WA State and CDC group safety guidelines in place when the course begin.
    • Upper Level students must be fully vaccinated to attend in-person courses; proof of vaccination is required.
    • Elementary, Lower and Middle Level students must wear a mask at all times.
    • Thank you in advance!
  • Students in both online and in-person classes take their practice tests at home via our online testing platform which provides an online answer sheet and automatic timing. 

We ensure that each child receives proper attention by limiting the number of students in our in-person and online courses.  If a course fills well in advance of its start date, we may open an additional section.

If your child needs extra help with math, our summer ISEE & SSAT Math Workshops can provide the knowledge and support they need!

  • Math workshops are also appropriate for students who need a general math refresher or who will take a placement exam such as the HSPT.
  • When preparing for a standardized exam, it’s best to take the math workshop prior to taking our comprehensive ISEE/SSAT course.
