1.2 Computer-Adaptive Testing (CAT) Mechanics, Session Timing & Technology-Enhanced Items

Quick Summary: The FAST ELA Grade 6 assessment utilizes a Computer-Adaptive Testing (CAT) engine on Cambium Assessment that adjusts item difficulty in real time based on student performance while strictly fulfilling the B.E.S.T. blueprint. Scheduled for 90 minutes in PM1/PM2 and 120 minutes in PM3 (including ~5 non-scored field test items), testing is protected by Florida's end-of-school-day untimed policy. Mastery requires targeted strategies across five Technology-Enhanced Item (TEI) formats.

The Computer-Adaptive Testing (CAT) Algorithm

Unlike fixed-form exams where all students receive identical questions, the FAST ELA Grade 6 assessment is fully computer-adaptive. Administered via the secure Cambium Assessment platform, the test dynamically adjusts question difficulty based on student responses.

How the Algorithm Operates

The CAT engine uses Item Response Theory (IRT) to continuously update an ability estimate (the student's theta value):

1. Starting Point: The engine opens with grade-level items and no confirmed ability estimate. FDOE does not publish the exact starting difficulty, so treat the first passage set as ordinary grade-level work.
2. Dynamic Recalibration: Each correct answer increases the ability estimate, prompting a more demanding subsequent item. An incorrect response lowers the estimate, prompting a less difficult item.
3. Blueprint Compliance: The engine strictly fulfills the Florida B.E.S.T. Grade 6 blueprint across three reporting categories:
   • Reporting Category 1: Reading Prose and Poetry (25–35%)
   • Reporting Category 2: Reading Informational Text (25–35%)
   • Reporting Category 3: Reading Across Genres and Vocabulary (35–50%)

Regardless of achievement level, the algorithm ensures a balanced distribution across all three categories.

Why Harder Questions Are a Positive Indicator

On a computer-adaptive exam, encountering increasingly difficult questions is a positive sign. If reading passages feature dense syntax, subtle character psychology, and intricate vocabulary, the engine has validated basic competency and is probing whether the student qualifies for Level 4 (Proficient) or Level 5 (Mastery). Conversely, overly simplistic passages indicate the engine is testing lower boundaries. Sixth graders must embrace challenging questions as evidence of strong performance.

Early Items Steer Trajectory

Because the ability estimate is least certain at the start, early questions exert substantial influence on the testing trajectory. Careless errors on early passages pull the ability estimate downward, requiring a longer sequence of correct answers later to recover. Deliberate, focused reading on the first two passage sets is essential.

Session Timing, Item Counts & The Untimed Policy

The FAST ELA Reading assessment adheres to structured scheduling parameters that vary between progress monitoring windows:

Field Test Items in PM3

During the spring PM3 administration, students receive approximately 5 non-scored field test items embedded seamlessly among operational items. FDOE uses these items to calibrate difficulty and evaluate distractor plausibility for future test pools. Because field items are indistinguishable from scored questions, students must treat every question with equal seriousness.

Florida's End-of-School-Day Untimed Policy

A central feature of Florida assessment policy is the untimed testing provision. While test schedules specify 90 minutes for PM1/PM2 and 120 minutes for PM3, Florida State Board of Education rules guarantee that any student actively working at the end of the scheduled session must be permitted to continue testing until the end of the regular school day.

Proctors may not force a student to submit their test or collect materials prematurely if the student is actively engaged in reading and answering questions. This policy eliminates time panic. Students should read carefully and verify evidence rather than racing against a clock.

Technology-Enhanced Item (TEI) Formats and Strategies

FDOE's test design summary describes traditional multiple-choice items plus a set of technology-enhanced items (TEIs). Five formats account for most of what a sixth grader sees; FDOE also lists two-part hot text and multimedia stimuli, and any of these may be combined into a single multi-part item:

Tactical Protocols for TEI Mastery

• Multiple Choice: Beware the "half-true" trap (first clause is true, second clause distorts) and literal recall traps (true passage details that do not answer the prompt). Predict the answer, then eliminate three flawed choices.
• Multiselect: Prompts instruct to "Select two" or "Select three" correct answers. Treat every candidate choice as an independent True/False statement verified against the passage.
• Selectable Hot Text: Beware the "neighborhood trap"—clicking an introductory background sentence rather than the specific sentence containing active textual proof. Verify that the selected line directly substantiates the claim in isolation.
• Evidence-Based Selected Response (EBSR): Use the Interlocking Check. Part A requires an analytical claim; Part B requires supporting evidence. If no Part B quotation directly proves your Part A choice, your Part A interpretation is flawed. Part B acts as a diagnostic mirror to confirm Part A.
• Table Match / Grid: Matrix items require checking boxes to classify arguments or structures across passages. Never look for visual patterns. Verify textual evidence for each row independently.
