## CasperPractice

CasperPractice is a specialist study platform for the CASPer situational judgment test, the open-response admissions assessment created at McMaster University and used by hundreds of health-science programs. Instead of generic chatbot feedback, the product runs a dedicated scoring model trained on a large corpus of real candidate answers, so responses are graded against the scale evaluators actually use and placed in a quartile band.

The workflow mirrors test day closely. You open a scenario, watch or read it once, and the timer starts; you then type or record a video answer exactly as you would in a live sitting. Within seconds you receive a quartile ranking, notes on specific sentences, and a rewritten version of your answer that demonstrates the reasoning a top-quartile response would show. A practice-test mode groups scenarios into full-length simulations so you can rehearse stamina and pacing, not just individual questions.

The library is broad — every major scenario type is represented, including ethics, empathy, collaboration, resilience, personal experience and media-based prompts. Progress accumulates across attempts, which makes it easy to spot recurring weaknesses such as one-sided arguments or unsupported claims. Free users can try the questions with limited AI coaching, while the paid Pro plan unlocks unlimited scoring and the 4th quartile guarantee, subject to stated conditions like answering a minimum number of questions with the same email used for the real test.

**Pricing & Plans:** Freemium. A free tier gives access to practice questions with limited AI coaching (the first attempts are coached at no cost), while the Pro plan is a paid subscription that unlocks unlimited scored attempts and the 4th quartile money-back guarantee. Pricing is discounted periodically on the site.

- **Realistic question bank and full mock tests:** Work through hundreds of typed, video and media-based scenarios, or take complete simulations that reproduce the CASPer sections, question order and per-question time limits.
- **Purpose-built AI scorer:** Answers are graded by a model calibrated on a large set of real CASPer responses, returning a quartile estimate rather than vague encouragement, plus sentence-level notes on what weakened the answer.
- **Instant answer rewrite:** After each attempt you get a stronger version of your own response, showing how to hold competing perspectives and land on a clear position without sounding rehearsed.
- **Competency coverage tracking:** Attempts are mapped to the competencies CASPer measures, so you can see whether ethics, communication or collaboration is dragging your average down and drill the weakest one.
- **4th quartile guarantee on Pro:** Pro subscribers who meet the conditions (minimum answered questions, matching email, official results forwarded in time) are refunded or keep lifetime access if they miss the top quartile.

**Strengths:** Purpose-built scoring model rather than a generic chatbot prompt; Quartile ranking and rewrites give concrete, comparable feedback; Full-length simulations mirror the real sections and time limits; Bonus: large free question set and a money-back guarantee on the paid plan

**Limitations:** Value depends on the accuracy of third-party AI scores, which only the official provider can truly validate; The free tier's coaching is limited, so meaningful practice volume requires a paid plan; Video-response practice still cannot replicate the pressure of a live proctored sitting

## ReadTheory

ReadTheory began as a free adaptive reading comprehension program and has grown into a full practice and assessment platform used by teachers, schools, and districts worldwide. Students read short passages and answer comprehension questions at their current level; the system adjusts difficulty after each answer, so a reader is always working just beyond their comfort zone rather than being stuck on content that is far too easy or far too hard. Teachers see live feedback data and can identify exactly where comprehension breaks down.

Reporting is one of its strongest draws. A single dashboard shows growth, mastery, and gaps at the student, class, school, and district level, expressed in Lexile measures, grade levels, and ELA standards. Beginning, middle, and end-of-year benchmark assessments are included at no extra cost, and schools report meaningful gains on state assessments after consistent use.

The content side combines a large human-written library of fiction and nonfiction with an AI worksheet builder that generates passages and questions on any topic in seconds. ReadTheory also keeps a strong offline component: passages, quizzes, graphic organizers, and worksheets can all be printed for small groups, substitute teaching, or any lesson where screens are not the answer. Onboarding is lightweight, with classes set up in about five minutes and no lengthy training required, and the platform is designed around student privacy and FERPA compliance.

**Pricing & Plans:** ReadTheory is free to start for individual teachers, students, and parents, and the company describes its core practice as free. Paid plans exist for schools and districts that need school-wide and district-level reporting, administrative tools, and broader support; specific pricing tiers should be confirmed with ReadTheory directly or through their sales team.

- **Adaptive leveled practice:** A quick benchmark assessment finds each student's true reading level in around 14 minutes, then the difficulty adjusts continuously as they practice.
- **AI worksheet builder and text library:** Generate reading passages and questions on any topic in seconds, or choose from thousands of standards-aligned fiction and nonfiction texts written by real authors.
- **Progress and standards reporting:** One dashboard shows growth, mastery, and gaps across every student, class, school, and district, reporting in Lexile, grade, and ELA standard terms.
- **Printable resources:** Passages, quizzes, graphic organizers, and worksheets are available to print for small groups, substitute days, and screen-free lessons.
- **Built-in benchmarks and privacy:** Beginning, middle, and end-of-year benchmarks are included at no extra cost, and the platform is FERPA compliant with transparent data practices.

**Strengths:** Free core adaptive reading practice for teachers and students; Automatic grading and instant feedback save substantial teacher time; Reporting covers students, classes, schools, and districts in Lexile, grade, and ELA standard terms; Built-in BOY, MOY, and EOY benchmarks at no extra cost
