Our Methodology
How we turn your responses into career insights — the frameworks, formulas, and scientific foundations behind every score.
Overview & Purpose
What This Assessment Measures
The SkillsBuff High School Assessment is designed to help students aged 14–18 discover career directions that align with their interests, values, and academic strengths. It is a career awareness tool, not a career prescription.
Discover which career families, industries, and university majors match your unique profile.
Understand your child's motivational drivers and how to support their exploration.
Use transparent, formula-backed insights to guide career conversations with evidence.
Plus subject grades/interests and aspiration questions — ~27 total inputs
Scientific Foundations
Established Career Psychology Frameworks
Holland's RIASEC Theory
Developed by psychologist John L. Holland in 1959, RIASEC is one of the most widely used and empirically validated frameworks in career psychology. It classifies people and work environments into six personality types arranged in a hexagonal model:
1. Explicit measurement: 3 scenario-based questions where each choice maps to one RIASEC dimension. Each selected dimension receives 33.33 points (max 100 if all 3 match the same type).
2. Subject inference: Academic subjects map to RIASEC dimensions (e.g., Physics → Realistic, Computer Science → Investigative). Each subject contributes: (interest × 0.6 + grade × 0.4) × 20
3. Merging: Final score = explicit × 0.70 + inferred × 0.30. Explicit responses carry more weight, but subject data helps fill gaps and validate self-reports.
4. Adjacency smoothing: Holland's hexagonal model predicts that adjacent types (e.g., R–I, I–A) share traits. We apply a 10% neighbor boost: smoothed = score + (left_neighbor × 0.10) + (right_neighbor × 0.10). This prevents artificially narrow profiles.
Schein's Career Anchor Theory
Developed by MIT professor Edgar H. Schein in 1990, Career Anchors represent the core professional values that a person will not give up, even under pressure. They predict long-term career satisfaction more reliably than skills or interests alone.
Step 1 — Base score: 8 Likert scale statements (1–5). Converted to: (rating − 1) × 12.5 producing a 0–50 base range.
Step 2 — Primary tradeoffs (4 pairs): Forced-choice “would you rather” questions pit paired dimensions against each other. Winner gets +30, loser gets −15.
Step 3 — Cross-cutting tradeoffs (2 pairs): These pit common co-winners against each other to break ties (e.g., Technical Excellence vs. Challenge). Winner gets +15, loser gets −8.
Step 4 — Clamp: All scores rounded and clamped to 0–100. Theoretical maximum is 95 (rate 5, win both tradeoffs).
Why tradeoffs? Rating all anchors “5/5” doesn't differentiate. Forced choices reveal what you truly prioritize when you can't have everything.
Foundation Clusters
8 Cognitive & Skill Dimensions
We derive 8 foundation clusters from your academic performance and reported skills. These represent cognitive and skill dimensions that predict success in different career families.
Each subject contributes a signal: (grade_signal × 0.60) + (interest_signal × 0.40) where signals are normalized to 0–100. Subject-to-cluster mappings are predefined (e.g., Mathematics → Quant Reasoning, English → Communication).
Skills and competencies contribute via keyword matching (e.g., “programming” → Logical Problem Solving). Final cluster score is the average of all contributing signals.
| Subject Example | Primary Cluster | Secondary Cluster |
|---|---|---|
| Mathematics | Quant Reasoning | Logical Problem Solving |
| Physics | Quant Reasoning | Systems Thinking |
| Computer Science | Logical Problem Solving | Systems Thinking |
| English / Literature | Communication & Writing | Research & Curiosity |
| Art / Design | Visual/Design Thinking | Communication & Writing |
| Business / Economics | Business/Market Thinking | Collaboration/Leadership |
| History / Geography | Research & Curiosity | Communication & Writing |
How Career Pathways Are Scored
Role Family Fit Algorithm
Career pathways (role families like “Builder (Software)” or “Data Analytics”) are scored using a composite formula that balances four dimensions:
Exceptional alignment across all four dimensions
Strong alignment across core categories
Potential fit — requires more skill exposure
Some families have hard prerequisites: Hardware/Embedded requires a Realistic (R) interest signal or Systems Thinking above 60, and AI/ML requires Quant Reasoning above 50 or an Investigative (I) signal. Without these, the capability score is halved to reflect the steeper learning curve.
How Roles Are Matched
Individual Role Fit Scoring
Within each career family, individual roles (e.g., “Frontend Developer”, “Data Analyst”) are scored with a weighted formula optimized for high school students:
At 14–18, students are still building skills. Research shows that interest alignment (RIASEC) and value fit (Anchors) are stronger predictors of long-term career satisfaction than current technical ability. That's why personality dimensions carry 55% of the weight, while existing skills carry only 20%.
How Industries Are Scored
Industry Fit Algorithm
Industries are scored as aggregates of the roles they contain. The intuition: if you're a strong fit for many roles within an industry, you'll likely thrive in that sector.
How Majors Are Suggested
University Major Fit Algorithm
Major suggestions help students explore which university degree programs align with their academic strengths and career direction. The formula prioritizes academic foundation because degree choice depends heavily on readiness.
We use cosine similarity — a standard vector comparison technique — to measure how “directionally aligned” two profiles are. Two profiles pointing in the same direction score near 1.0, even if their absolute magnitudes differ. This means a student with moderate but well-distributed scores can still match strongly with the right major.
Limitations & Disclaimers
Important Context for Interpreting Results
This assessment is designed to spark exploration and conversation. It does not determine your career. Use it as one input among many.
All scores are based on your own responses. Accuracy depends on honest, thoughtful answers. Social desirability bias (answering how you think you 'should') can distort results.
With ~27 questions, we cannot capture every nuance. RIASEC is measured with only 3 scenario questions plus subject inference — some personality dimensions may be underrepresented. Professional RIASEC assessments typically use 30-60 items.
Career interests are not fixed, especially during adolescence. We recommend retaking the assessment every 6-12 months to track how your profile develops over time.
This assessment measures interest alignment and value fit. It does not measure cognitive ability, aptitude, or intelligence. A low score in a career family does not mean you lack the ability to succeed there.
While built on established frameworks (Holland's RIASEC, Schein's Career Anchors), this tool should complement — not replace — guidance from qualified career counselors, teachers, and mentors.
Career assessments developed in Western academic traditions may not fully capture the values, constraints, and opportunities of every cultural or socioeconomic context. Interpret results with your own lived experience in mind.
Our formulas use specific weights (e.g., 30% Interest, 25% Capability) that reflect professional judgment informed by career psychology literature. These are not absolute truths — they are reasoned design decisions that we make transparent here.
SkillsBuff provides career guidance and learning resources. Outcomes depend on individual effort, market conditions, educational choices, and many other factors beyond the scope of any assessment.
