Choosing the best online ISEE prep courses comes down to three things: your child's learning style, your budget, and how much score improvement you're aiming for. With 15+ providers competing for parents' attention, picking the right one means cutting through the marketing and comparing the features that actually move the needle on test day. This guide ranks the top seven online options by price, practice test depth, and best-fit student profile.
We focused on seven providers that consistently appear in parent recommendations and review aggregators: Piqosity, Test Innovators, The Princeton Review, Kaplan, Study.com, Manhattan Review, and Tutorverse. Below is the at-a-glance summary, followed by quick takes on each. The full pricing breakdown is later in the article.
| Course | Format | Starting Price | Practice Tests | Best For |
|---|---|---|---|---|
| Piqosity | Self-paced + virtual tutor | Free / $99 / $199 | Up to 12 (advertised) | Practice test volume |
| Test Innovators | Self-paced + live crash | $85+ (single test) | 1–6 by tier | Adaptive practice + ERB partner |
| The Princeton Review | Private tutoring | $450–$3,000 | Included in package | Major score gap or retake |
| Kaplan | Self-paced (SSAT+ISEE) | $299 | Included | Two-test households |
| Study.com | Video + practice library | Subscription (free 15-Q diagnostic) | 60+ practice tests | Video-first learners |
| Manhattan Review | Live online + tutoring | By quote | Included in package | Structured live instruction |
| Tutorverse | Small-group + on-demand | $175 (on-demand) and up | Multiple | Small-group live setting |
Piqosity advertises up to 12 full-length practice tests on its ISEE product page — more than any other ISEE prep course we found. The pricing is unusually transparent: a free On-Track plan with 2 practice tests and a mini diagnostic, an Honors plan around $99 with roughly 5–6 practice tests and 300+ questions, and an Advanced plan around $199 with the full content library and the largest practice-test allotment. All paid plans include 365-day access with no recurring charges, an adaptive practice engine, and a virtual tutor named Patrick that walks students through answer explanations.
Where Piqosity stands out is the volume of timed practice content available at a price point most families can absorb without negotiation. The trade-off is that there's no live instructor — a self-motivated student will love it, while a child who needs accountability may struggle to make consistent progress.
Test Innovators is the official ERB partner for ISEE practice and is featured prominently across the iseepracticetest.com domain. Their package pricing starts around $85 for a single practice test and scales with bundles. They run monthly live online crash courses for $275 (3 hours) and offer the same content as on-demand for $175. Subject-specific live classes run $185 each, with bundle discounts at $350 for two and $495 for three.
The adaptive learning technology is a real differentiator: tracking practice test results to highlight where the student should focus next. Small group sizes (12–15 students) keep the live classes interactive without losing the structured curriculum.
The Princeton Review's ISEE offering centers on private tutoring across three tier packages (3, 10, and 24 hours), with pricing roughly between $450 and $3,000. They include full-length practice tests and workbooks in their tutoring packages. Princeton Review does not offer a "Higher Score Guarantee" specifically for the ISEE — buyers should weigh that against the tutoring cost.
Kaplan's standout offering is a self-directed class that prepares students for both the SSAT and the ISEE for $299. For families with children planning to apply to schools that accept either exam — or for households with siblings testing in different windows — the bundled price is hard to beat. Kaplan also offers one-on-one tutoring and live, interactive online prep classes at higher price tiers.
Study.com runs three ISEE courses tailored to grade levels: Lower Level (118 lessons), Middle Level (140 lessons), and Upper Level (253 lessons). The platform includes 60+ practice tests and 100+ hours of video instruction across the broader subject library, plus 24/7 expert help. New users can take a free 15-question diagnostic to identify gaps before committing. Pricing is subscription-based and lives on the Plans page rather than the courses page.
Manhattan Review offers ISEE prep through on-site group courses, one-on-one tutoring, and online interactive courses. They confirm that their online classes use the exact same instructors and content as classroom courses — so families choosing online aren't getting a watered-down product. Pricing isn't published on the main page; expect to schedule a consultation to receive a quote.
Tutorverse runs small-group, live ISEE prep classes both in-person in Manhattan and online in East and West Coast time zones. Their on-demand alternative starts at $175 (Upper Level 20-unit course) and serves students who can't fit a live class into their schedule. The small-group live format hits the middle of the price-vs-personalization curve.

The format decision matters as much as the provider. Self-paced ISEE online classes work for self-motivated readers; live courses suit students who need external structure; private tutoring delivers the largest per-hour gains for big score gaps. Here's the side-by-side.
| Feature | Self-Paced | Live Online Group | Private Tutoring |
|---|---|---|---|
| Schedule flexibility | Highest — study anytime | Fixed weekly meeting | Scheduled with tutor |
| Live instructor access | Limited or add-on | Included during class | Always included |
| Personalized to student | Adaptive analytics | Group-paced | Fully personalized |
| Typical price range | $99–$299 | $175–$999 | $450–$3,000+ |
| Best for | Self-motivated students | Need accountability | Major score gap, retake |
Self-paced courses are the dominant model for online ISEE prep. They give students full control over pacing — reviewing material at their own speed, slowing down on weak areas, and skipping concepts they already know. The flexibility makes them a strong fit for families with packed extracurricular schedules, since the student can put in 30 minutes after homework instead of blocking out a 2-hour evening class.
The catch: self-paced only works when the student is self-motivated. A distractible 6th-grader put in front of an unsupervised platform tends to drift — the structure that drives consistent practice has to come from somewhere, whether it's a parent-set schedule or the student's own discipline.
Live classes solve the consistency problem. The fixed schedule means the student shows up whether they feel like it or not, and the instructor adjusts pacing in real time based on the room. Test Innovators' 3-hour crash courses ($275) and Tutorverse's small-group sessions are the most accessible options here — both deliver structured curriculum without 1-on-1 pricing. Manhattan Review's online classes use the exact same instructors and lecture content as their in-person sessions.
The trade-off is the schedule itself. If your child has Tuesday-Thursday-Saturday commitments, a Wednesday-night class doesn't help — and missing one or two sessions in a 6-week course meaningfully degrades the experience.
Private tutoring delivers the largest gains per hour because every minute is targeted at the student's specific weak areas. A skilled tutor can move a student 2 stanines in fewer total hours than a self-paced course because there's no time spent on already-mastered content. Princeton Review and Manhattan Review's tutoring offerings sit at the top of this market, with packages from $450 up to $3,000+.
Worked Example
Imagine two 7th-graders both targeting a stanine 8 on the Middle Level ISEE. Maya is a self-motivated reader who enjoys solving puzzles independently. Jordan thrives on classroom discussion and tends to lose focus when working alone for more than 20 minutes.
ISEE prep course pricing spans almost two orders of magnitude — from free to $3,000+ — so understanding what's actually included at each tier matters more than picking the highest absolute price. Here's how the live online ISEE course landscape and self-paced options break down.
The cheapest serious entry point is Piqosity's free On-Track plan, which includes 2 full-length practice tests plus a mini diagnostic. Study.com offers a free 15-question diagnostic on signup. ERB itself provides a small free practice sample through the official portal. Test Innovators' single-practice-test packages start around $85.
At around $99, Piqosity's Honors plan unlocks roughly 5–6 full-length practice tests and 300+ practice questions. For most first-time test-takers on a budget, this is the right starting point — the practice volume is comparable to courses three to four times the price.
The middle of the market is dominated by self-paced video and practice platforms. Piqosity Advanced at around $199 unlocks the full practice-test allotment (up to 12 advertised) and the bundled English and Math content libraries. Kaplan's self-directed SSAT-and-ISEE bundle is $299 — exceptional value for households with siblings or students applying to schools that accept either exam.
Test Innovators' on-demand crash course ($175) and Tutorverse's Upper Level on-demand course ($175) round out this tier with structured video instruction that mirrors the live class content.
| Starting Stanine | Achievable Goal | Typical Time Required | Difficulty |
|---|---|---|---|
| 3–4 | 5–6 stanine | 8–10 weeks of structured prep | Easier — solid content review drives big gains |
| 5–6 | 7–8 stanine | 10–12 weeks with timed practice | Moderate — strategy and pacing matter more |
| 7 | 8 stanine | 12+ weeks with targeted weakness work | Harder — diminishing returns at high end |
| 8 | 9 stanine | Often not worth the time investment | Hardest — only top 3% of testers earn a 9 |
Test Innovators' live 3-hour crash course is $275, with subject-specific live classes at $185 each (bundles at $350 for two, $495 for three). Their summer prep program is $999 standard ($1,099 late registration) for a 5-day intensive that includes mock testing. Tutorverse small-group sessions and Manhattan Review's class-based offerings sit in this range too.
Premium tutoring is where Princeton Review and Manhattan Review compete. Princeton Review's tutoring tiers cover roughly 3-, 10-, and 24-hour packages from $450 up to $3,000+. Manhattan Review prices by quote — expect to schedule a consultation. The math here is straightforward: at the high end, you're paying for a senior tutor's time, customized lesson plans, and weekly progress reports.

Once you've narrowed by format and price, ISEE test prep courses still differ on five features that drive most of the score variance: practice test count, video lessons, adaptive technology, instructor access, and level-specific content.
Practice tests under timed conditions are the highest-ROI feature in any ISEE prep course. They replicate exam pacing, expose weak topic areas, and build the stamina required for a 2-hour-40-minute Middle or Upper Level test. Aim for at least 4–6 full-length practice tests in a course; under-tested students consistently struggle most with timing, not content.
Piqosity advertises up to 12 full-length practice tests, the most of any provider we surveyed. Test Innovators offers 1–6 depending on tier. Study.com's platform includes 60+ shorter practice tests across the broader subject library.
Video instruction reinforces tricky concepts that text-based explanations can muddle, especially for visual learners. Look for bite-sized video — anything over 15 minutes risks attention drift, particularly for younger students. Study.com leads on raw volume (100+ video hours across the platform), while Piqosity offers 60+ targeted concept lessons. Kaplan and Princeton Review include video as part of their bundled packages.
Adaptive learning identifies weak areas automatically and surfaces additional practice in those topics. Test Innovators and Piqosity both include adaptive engines — Piqosity describes its as gamified and personalized, with strengths-and-weaknesses analysis after every diagnostic. Kaplan's self-paced course is more linear, which is fine for a student who already knows their weak areas going in.
Self-paced ISEE prep platforms typically gate live tutor access behind tutoring add-ons. Manhattan Review and Princeton Review tutoring packages include direct tutor access by definition. Some self-paced courses (Study.com) advertise 24/7 expert help via Q&A — a useful safety net but not a substitute for scheduled instruction. Decide upfront whether your child needs live help or thrives with written explanations.
The ISEE has four levels with distinct content depth. Lower Level applies to grades 5–6, Middle Level to grades 7–8, and Upper Level to grades 9–12. Vocabulary difficulty rises sharply between levels — a typical Upper Level word appears 100x less frequently in printed text than a Lower Level word. Make sure the course you buy targets your child's level explicitly.
| Level | Grade Applying To | Total Test Length | Math Achievement Section |
|---|---|---|---|
| Lower | Grades 5–6 | Approximately 2 hours 20 minutes | 30 minutes |
| Middle | Grades 7–8 | 2 hours 40 minutes | 40 minutes |
| Upper | Grades 9–12 | 2 hours 40 minutes | 40 minutes |
ISEE course reviews tend to crown one "winner" — but the right course depends entirely on the student. Here's the matrix we use when parents ask for a single recommendation.
The deciding framework is simple but underused: diagnose first, set a target, match format, and plan the timeline. Skip any of those steps and you risk buying the wrong course or starting too late to use it well.
Before buying any course, take a free diagnostic to surface weak areas. Piqosity's mini diagnostic, Study.com's free 15-question diagnostic, and the ERB official sample are all free. The diagnostic tells you whether your child needs heavy content review (low stanines across all sections) or targeted weakness work (uneven section scores).
Identify the stanine your target schools expect. Most top private schools look for 7+ across all four sections. Many competitive schools accept 6+. The gap between current and target stanines determines how much course depth you need to buy and how much time to budget.
Be honest about your child's focus pattern. Self-paced ISEE prep works for self-motivated learners. Live online ISEE classes deliver accountability for distractible students. Private tutoring is the right answer for major score gaps or retake plans.
Plan for 8–12 weeks of consistent prep at 4–6 hours per week. Build in a full-length practice test every 2 weeks. Students aiming to improve by 2+ stanines should plan toward the longer end of that range.
Add roughly $30–$60 for an official practice book even when buying a digital course. The paper version of the ISEE is still common at many test sites, and physical practice helps students get comfortable with the bubble-sheet format.
