Product Case Study / Cognitive Assessment Platform
Feuerstein Digital Assessment Platform
B2B EdTech • Cognitive Assessment • Sole Product Designer
Core challenge
This was not a clean-slate project. Development was already moving, but the product had no consistent UX/UI foundation. I had to introduce structure while preserving delivery momentum, supporting sensitive users, and translating complex assessment rules into reliable digital behavior.
I joined after development had already started. As the sole product designer for 2.5 years, I had to design forward while repairing the foundation — turning printed assessment logic and an active early build into a coherent production platform without stopping delivery.
* Due to the commercial nature of this platform, selected workflows, configurations, and business content were intentionally modified to protect sensitive business information.
Role
Sole designer for 2.5 years: UX, UI, accessibility.
Platform
Guided tests, role-based management, analytics, reports.
Users
Children, educators, clinicians, institutions, adult candidates.
Scope
Printed tests, timed flows, data capture, reports.
01 / PRODUCT AND USER PROBLEM
Designing forward while repairing the foundation
I inherited an active build, printed assessment logic, multiple roles, timed workflows, reports, and no consistent UX/UI foundation. The priority was not to redesign everything at once, but to stabilize the product lifecycle and create reusable logic that could support delivery as the system expanded.
Printed tests became digital logic
Paper instructions, timing, scoring, forms, and reporting rules had to become clear product states.
An active build, not a blank canvas
Structure had to be introduced without stopping development. Decisions were phased around the highest-risk workflows first.
Sensitive users shaped the system
Children with special needs and attention challenges required calm screens, predictable feedback, and reduced cognitive load.

Cognitive load principle
In assessment environments, extra choices and unclear states increase cognitive effort. The interface had to show only what mattered now: status, progress, and the next action.
Professional context
The UX had to support varied cognitive and learning profiles
The product supported structured assessment and learning workflows, not self-diagnosis. It had to remain clear for participants with different attention, communication, language, motor, and learning needs while still serving professional teams.

01
Autism Spectrum Disorder (ASD)
Communication, sensory, and interaction patterns that affect how instructions and feedback are understood.
02
Attention and self-regulation
Focus, impulse-control, organization, and task-completion needs without assuming intellectual disability.
03
Developmental and language profiles
Language, cognition, motor planning, and social-skill differences required predictable screen behavior.
04
Specific learning differences
Reading, writing, math, and task-processing differences shaped the need for clear states.
02 / USERS AND ROLES
Users expanded from children to professional evaluation contexts
The product began with assessments for children and adolescents, helping professionals identify learning strengths, weaknesses, and suitable intervention paths. Over time it expanded into evaluation workflows for adults, professional candidates, and organizations assessing fit for roles, training, or certification paths.

Children and adolescents
Children and adolescents needed calm, predictable screens that supported focus during assessment tasks.

Educators and psychologists
Educators and psychologists needed reliable ways to run assessments and interpret outcomes.

Administrators
Administrators needed to manage users, permissions, tests, reports, and institutional workflows.

Adult candidates
Adults were later assessed for role fit, training programs, or professional authorization decisions.

Institutions and organizations
Institutions needed structured outcomes, printable reports, and group-level analysis.
03 / PRODUCT ECOSYSTEM
A role-based assessment ecosystem, not a single test screen
The platform had to connect printed assessment logic, existing admin operations, multiple user roles, timed testing, reports, and localized versions into one coherent product ecosystem.

04 / PRODUCT DECISIONS
Product judgment under active-development constraints
The work was less about following a fixed UX sequence and more about choosing what to stabilize first, what to preserve, and what to simplify as evidence and constraints changed.
Define the full lifecycle
Covered setup, permissions, delivery, data capture, reports, and analytics as one product flow.
Design for cognitive clarity
Used restrained colors, predictable layouts, and visible states for sensitive assessment contexts.
Separate roles and permissions
Created distinct workflows for administrators, educators, assessors, and participants.
Support reporting and analysis
Made printable outputs and analytical views part of the core platform, not an afterthought.
Build for phased expansion
Kept patterns flexible enough for nine tests and later adult evaluation contexts.
Stabilize UX after development began
Introduced structure and design logic after several months of development to reduce product risk.
05 / HOW THE WORK EVOLVED
The process was not linear. The product evolved as new evidence and constraints appeared.
I moved between product logic, interaction design, implementation support, and Design QA as the build progressed. Each stage exposed new constraints, so priorities changed without restarting the entire product.

06 / PRODUCT MODULES
Product screens that made the system tangible
A visual overview of the main product surfaces delivered across intake, timed testing, education-staff operations, reports, and professional review.
07 / DEEP DIVE
Deep dive: one Word Organization assessment
This sample shows the detailed UX work behind one assessment: word banks, answer zones, RTL layout, selected states, scroll behavior, timers, and reliable progress.
ONE TEST SAMPLE
roughly 5% of the total test work

Structure
Word bank and answer zones
Word bank, answer fields, timer, and progress had to work as one screen.

Selection
Choosing relevant words
Selected states stayed visible while students mapped words.

Placement
Mapping words to answer zones
Drag, scroll, and answer states had to stay clear in RTL layout.

Progress
Maintaining reliable task flow
Timers, navigation, and completion feedback had to support timed assessment validity.
08 / UX PRINCIPLES
What I deliberately did not optimize for
I did not optimize for visual novelty. In assessment contexts, cognitive clarity, predictable states, role separation, and low visual noise mattered more than expressive UI. The interface had to help users complete sensitive tasks reliably.

Cognitive clarity
Focused layouts, restrained colors, and low visual noise helped users stay oriented during assessment tasks.

Predictable feedback
Visible states, clear errors, and consistent controls reduced uncertainty during timed and guided tasks.

Reusable product patterns
The same interaction logic supported setup, delivery, monitoring, reporting, localization, and future tests.

09 / BEFORE AND AFTER SCREENS
Before and after screens: from legacy management to a redesigned platform
The before section uses a screen recording of the old management system. The after section uses a collage of redesigned screens to show the scale of the product change.
Before

After
Redesigned product platform

10 / OUTCOME
From fragmented assessment logic to a scalable product foundation
The result was not a one-time redesign. It was a reusable product system that could absorb additional tests, languages, institutions, and adult evaluation workflows while preserving consistent interaction logic.
What changed
Printed and manual assessment processes became one structured digital ecosystem.
What improved
Teams gained clearer management workflows while participants received calmer, more predictable task screens.
What the work enabled
The same product logic could support more tests, languages, institutions, and adult evaluation workflows.
