Raw Score to Scaled Score Converter

A raw score is simply the number of questions you answered correctly. On the LSAT and STAAR there is no penalty for wrong or blank answers, so your raw score is just your count of correct answers.

The raw score is your count of correct answers; the scaled score is the number actually reported (for example 120–180 on the LSAT, or a four-digit number on STAAR). The scaled score is produced by converting the raw score through an official conversion table.

Because of equating: each test form gets its own conversion table, and the mapping is not linear. For example, on the STAAR Biology EOC (December 2025) raw 25 converts to 3992 and raw 26 to 4000 (a gap of 8), while on Grade 8 Social Studies (Spring 2025) raw 48 converts to 6054 and raw 49 to 6550 (a gap of 496). One fixed formula cannot reproduce that shape.

LSAC does not publish one generic table. Every LSAT form has its own equated conversion table, so there is no single official raw-to-180 mapping. This tool's LSAT mode is an honest linear approximation: for example, 58 correct out of 77 gives a linear estimate of 165 on the 120–180 scale. Treat it as a rough estimate, not an official conversion.

They are STAAR performance levels. On the Biology EOC (December 2025) the published cut scores are Approaches 3550, Meets 4000, and Masters 4531. For example, a raw score of 37 converts to 4520 (Meets), while a raw score of 38 converts to 4531 (Masters).

STAAR conversion tables are built per administration through equating, so the table depends on the subject, grade, and test date. This calculator includes the official TEA tables for Grade 8 Social Studies (Spring 2025) and Biology EOC (December 2025); always use the table published for your exact administration.

No. It is an unofficial estimate for study planning. The STAAR tables are transcribed from official Texas Education Agency documents (labeled with source and year), and the LSAT mode is a linear approximation. Verify important scores against the official TEA or LSAC materials.

It maps your raw score linearly onto any scale: scaled = minimum + (raw ÷ total) × (maximum − minimum), rounded half-up to a whole number. For example, 75 correct out of 100 on a 200–800 scale maps to 650.

Equating is the statistical process testing programs use so that a reported score represents the same skill level regardless of which test form you took. Slightly harder forms get slightly more generous conversion tables and easier forms get stricter ones, which is why every form needs its own table.

A test grade calculator turns correct answers into a percentage and a letter grade (for example 47/50 = 94%, an A). This tool converts a raw score into the reported scaled score of a standardized test through its official conversion table — a different job.
