How SBTI Scoring Works - 30 Questions to 27 Types
See how SBTI turns 30 questions into 15 dimension scores, L/M/H levels, personality DNA, and a distance-based type match.
Last updated: 2026-05-07
Quick Answer
SBTI works by scoring 30 answers into 15 dimensions, converting each dimension into L, M, or H, then matching that pattern against a library of 27 personality type profiles.
- Each dimension is based on two situational answers.
- The final type is a closest-pattern match, not a single yes-or-no rule.
- The 16-digit DNA stores dimension scores for sharing and friend matching.
30 questions, zero randomness
The test has 30 situational questions. Each option has a score from 1 to 3, and each dimension is covered by two questions.
From scores to L/M/H levels
Two answers create a 2-6 score for each dimension. Scores of 2-3 become L, 4 becomes M, and 5-6 become H.
Pattern matching against 27 types
The system compares the user profile with original type patterns and ranks the closest matches by distance and exact dimension hits.
Result encoding: the DNA share code
The DNA code stores the 15 dimension scores plus a hidden-type flag. It allows result links and friend matching without uploading personal information.
Frequently Asked Questions
How is the SBTI score calculated?
Two answers form each 2-6 dimension score; those scores are converted into L, M, or H levels and compared with type patterns.
Why can two close results appear similar?
Neighboring types may share many L/M/H levels. The match percentage and exact-dimension count explain how close the result is.
Does the DNA code include my name or email?
No. The DNA code is a compact score string, not a personal identity record.
