Calculator based on 2025 NGSSS Standards (325-475 scale)
Remember: Live test is adaptive; practice PDFs are linear
2 Back-office magic: raw ➜ scale
- Concurrent calibration & IRT. All Bio forms are calibrated together, anchoring the statewide mean at 400.
- Equating to the NGSSS 325-475 scale. Your theta (θ) is linearly mapped so spring, summer, or winter forms stay apples-to-apples.
- Rounding & reporting. The whole number score lands in the Florida Reporting System within 24 hours.
Reality check: each operational form has its own secret conversion key. Charts online are practice estimates only.
3 Achievement levels & cut scores (official NGSSS)
| Level | Scale score | Dashboard calls it |
|---|---|---|
| 5 | 431 – 475 | Mastery |
| 4 | 421 – 430 | Proficient |
| 3 * | 395 – 420 | On Grade / Pass |
| 2 | 369 – 394 | Below satisfactory |
| 1 | 325 – 368 | Inadequate |
Passing cut score = 395 (bottom of Level 3).
4 Why the score matters
| Bucket | Impact |
|---|---|
| Course grade | Counts for 30 % of final Biology 1 grade statewide. |
| Graduation | Not a must-pass for a standard diploma, but Level 3+ is required for the “Scholar” designation. |
| Accountability | Districts roll Level 3-plus rates into science KPI dashboards. |
5 Worked example (illustrative)
| Step | Student A |
|---|---|
| Raw correct | 37 / 52 ≈ 71 % |
| Scaled score | 404 |
| Achievement level | Level 3 ➜ Pass |
6 DIY practice-test goalposts
- Score your practice set’s raw points.
- Use any public conversion as a ballpark—expect ±10 drift on the live form.
- Aim for an estimated 410+ in practice to cushion above the 395 line.
- Remember: the live test is adaptive; linear PDFs can feel easier.
7 Quick FAQ
| Q | A |
|---|---|
| Does the built-in calculator matter? | FD OE gives a four-function pop-up—no graphing tricks here. |
| Can a high Bio score offset a low Geometry? | No cross-credit; each EOC stands alone for course grade & scholar seal. |
| Retakes? | Offered fall, winter, spring, summer—only the highest scale score sticks. |
| Superscoring? | Universities still want SAT/ACT for STEM programs. |
