From first diagnostic to exam day

Every certification follows the same path, aligned to the blueprint the certifying organization publishes.

Aligned to the published blueprint
We start from the exam blueprint the certifying organization publishes: every domain, every objective, and how much each one is weighted. Each objective is matched to the lessons that teach it. Where nothing we have covers an objective, we build a new lesson or lab for it.
Adaptive readiness diagnostic
Students take a short adaptive test that measures readiness on every exam objective. It starts where the exam puts the most weight and adjusts with each answer, so most students finish in about 35 questions or fewer.
A study plan for each student
Results show readiness objective by objective and turn into a personal study plan. The plan skips what the student already knows and orders the rest so foundational skills come before the topics that build on them.
Study with a tutor, prove mastery
Each lesson comes with Socrat Tutor Agent. Miss a practice question and the tutor points back to the concept and asks the student to reason it through. Students retry only what they missed, and move on once they've shown mastery.
Hands-on where the exam demands it
Some objectives are skills to perform, not facts to recall. For those, students complete hands-on labs with safety steps and measurements checked against the required tolerances.
Sit the exam
Exams are delivered by the certifying organizations and their authorized testing providers. For many certifications, remote proctored exams are available through Pearson Certiport. The certifying organization scores the exam and awards the credential.

A closer look at the exams

Details on some of the certifications and exams we prepare students for, in alphabetical order. Core-LX prepares students; the certifying and testing organizations administer the exams and award the credentials and scores.

ACT WorkKeys

National Career Readiness Certificate, aiming for Gold

The certificate employers and state accountability systems ask for. WorkKeys hands students a table, a floor plan or a policy and asks what they can do with it, so the course teaches working from the source in front of you, not memorizing.

All three assessments: Applied Math, Graphic Literacy and Workplace Documents
Every objective at Levels 3 to 5, with Level 6 as stretch work
Timed practice forms at the real exam's length
One semester, designed for grades 11 and 12

ARRT

Radiologic technology credentials from the American Registry of Radiologic Technologists

Self-paced prep for radiologic technologists advancing to the radiologist assistant role, mapped to ARRT's published content specifications.

Registered Radiologist Assistant (R.R.A.): all 39 objectives across 7 content areas
ARRT awards the credential once the candidate passes the exam and meets its other requirements

ASVAB

Military entrance and career placement

The ASVAB decides whether a student can enlist and which military careers they qualify for. Our prep finds the weak spots in each subtest and teaches to them.

All nine subtests, including the four that make up the AFQT score
Adaptive diagnostics that route students to the lesson for each skill they miss
A full lesson for every skill tested, each ending with review and practice
Reading and vocabulary lessons that teach strategies for passages students haven't seen

GED

High school equivalency for adult and returning learners

Preparation for all four GED subject tests, starting from each learner's actual gaps rather than from page one.

Mathematical Reasoning, Reasoning Through Language Arts (including the extended response), Science and Social Studies
20 units covering 209 skills
A diagnostic and a practice test for every subject
A full-length mock GED before test day

OSHA 10-Hour General Industry

Workplace safety, taught through the hazards of the student's own field

The OSHA topic list stays the same in every industry. The hazards that bring it to life don't. Our culinary and healthcare tracks teach hazard recognition in a commercial kitchen and in a clinical setting.

Culinary and foodservice track: 64 objectives, with kitchen walkthrough labs and an on-screen kitchen for schools without one
Healthcare track: 73 objectives, for grades 9 to 12
Preparation and aligned instruction. The OSHA 10 card is issued by an OSHA Outreach authorized trainer.

ProStart

The National Restaurant Association's two-year culinary and restaurant management program

Aligned to Foundations of Restaurant Management and Culinary Arts, Levels 1 and 2, from kitchen basics and food safety through cost control, menus and management.

44 units covering 311 learning objectives
Culinary skills, front-of-house service, management and marketing
The National Restaurant Association awards ProStart credentials on completion of its assessments

ServSafe Manager

Food Protection Manager certification from the National Restaurant Association

Prep aligned to the published exam blueprint across all seven domains, with an adaptive diagnostic and a personal study plan.

Every domain of the 90-question, two-hour exam
A diagnostic that finds each student's gaps before study starts
Pairs with ProStart and OSHA 10 Culinary for a complete culinary pathway

TSIA2

Texas college readiness and dual-credit eligibility

For Texas juniors and seniors who want dual credit, and for adults heading back to college, so they start in credit-bearing courses instead of remediation.

All 67 published TSIA2 objectives, across math and English language arts and reading
A short diagnostic at the start of each unit, so students skip what they know
Spoken practice sessions with an AI coach before each unit and each quiz
Self-paced, with no fixed schedule

Prep that builds understanding, not pattern memorization

Students who memorize answer patterns pass practice tests and stall on the real exam. Our prep is built so students understand why an answer is right.

Practice-test prep compared with Core-LX certification prep
Practice-test prep	Core-LX certification prep
Everyone works through the same question bank	A diagnostic finds each student's gaps, and the plan targets only those
A wrong answer reveals the right one	The tutor asks questions until the student can explain the right answer
Completion means reaching the last page	Progress requires demonstrated mastery of each objective
Readiness is a guess until exam day	Readiness is measured objective by objective, against the exam's own weighting
Wrong answers are filler	Wrong answers are written from the mistakes test-takers actually make, so each miss shows what to fix
Skills objectives get a reading assignment	Skills objectives get a hands-on lab

What's inside

A diagnostic that measures

The readiness diagnostic gives no hints and no tutoring, so the score reflects what the student knows. Missing a foundational skill lowers readiness for the topics that depend on it.

Calibrated questions

Every exam objective has its own set of questions, written at the objective's difficulty. Each comes with an explanation of the right answer and the mistake behind each wrong one.

Readiness results students understand

Results show strengths and gaps by objective, with a short plain-language summary of where to focus first.

A readiness view for teachers

See every student's readiness for the certification, a class heatmap of weak objectives, and alerts when a student keeps missing the same concept.

Accessible and multilingual

Diagnostics and lessons can be read aloud and translated, so students are measured on the skill, not on their English.

Inside your LMS

Students take diagnostics and lessons in Canvas, Schoology, Moodle, D2L or Blackboard. Scores sync to your gradebook.

Common questions about test prep

More questions and answers

What is diagnostic, prescriptive test prep?

Each student takes a short adaptive diagnostic that measures readiness on every objective in the exam's published blueprint. The results become a personal study plan covering only what the student hasn't mastered, studied with an AI tutor and gated on demonstrated mastery.

How long is the readiness diagnostic?

The diagnostic adapts with each answer and starts where the exam puts the most weight, so most students finish in about 35 questions or fewer.

Who awards the certification?

Our test prep is aligned to each exam's blueprint as published by the certifying organization. We partner with the certifying organizations to provide exam vouchers, and students sit the exam with the certifying organization or its testing provider, which scores the exam and awards the credential.

Where do students take the certification exam?

Exams are delivered by the certifying organizations and their authorized testing providers. For many certifications, remote proctored exams are available through Pearson Certiport.
