Which Accountability Model Applies to Your School?

Mississippi uses two point-based models. The model depends on whether your school serves students in 12th grade. Both share the same growth and proficiency components — the key difference is the addition of Graduation Rate and Readiness for schools with 12th grade.

🏫
Schools Without Grade 12

700-Point Model

Applies to elementary, middle, and K–8 schools. Scored on 7 components, each worth 100 points (700 total). Reading and Math each have two growth components: one for all students, one for the Lowest Performing 25% subgroup.

The 7 Components (per MDE document p. 37)

700-Point Components

  1. Reading Proficiency
  2. Reading Growth – All Students
  3. Reading Growth – Lowest Performing 25% Student Subgroup
  4. Math Proficiency
  5. Math Growth – All Students
  6. Math Growth – Lowest Performing 25% Student Subgroup
  7. Science Proficiency
Each component = 100 points max · Total = 700 pts
🎓
Schools With Grade 12

1,000-Point Model

Applies to high schools and K–12 schools. Scored on 9 components. Graduation Rate is worth 200 points (×2.0 multiplier). Readiness is worth 150 points total (three 50-pt sub-components).

The 9 Components (per MDE document p. 37)

1,000-Point Components

  1. Reading Proficiency (100 pts)
  2. Reading Growth – All Students (100 pts)
  3. Reading Growth – LP25% Subgroup (100 pts)
  4. Math Proficiency (100 pts)
  5. Math Growth – All Students (100 pts)
  6. Math Growth – LP25% Subgroup (100 pts)
  7. Science Proficiency (50 pts)
  8. Graduation Rate – All Students (200 pts · ×2.0)
  9. Readiness: Acceleration + Achievement + Assessment (150 pts)
⚠️ Key difference from the ES/MS model: Science Proficiency drops to 50 points (not 100) in the HS model. Readiness is 150 points total — three sub-components at 50 pts each. There is no separate "Attendance" component in either model.

Participation Rate (§4.1): If fewer than 95% of enrolled students test, the denominator for all proficiency components is automatically set to 95% of enrollment — not the actual tested count. This inflates the denominator, reducing points. It also triggers an automatic drop of one performance classification (letter grade). Participation rates are not rounded.  |  N-Count (§3.1.1): A school must have a minimum of 10 valid test scores per component. If not met, up to 3 years of prior data can be combined.

Business Rule §6 · §6.2 · §6.8

How Is Student Growth Actually Calculated?

Growth in Mississippi is not a percentile ranking — it is a binary determination of whether each student moved up in proficiency level from one year to the next. Understanding this distinction is critical for school leaders.

§6.1 — What Counts as Growth?

Growth = Proficiency Level Movement

A student is counted as meeting growth if they meet ANY of the following criteria from one year to the next:

  • An increase of ANY performance/proficiency level
  • Staying at Proficient from one year to the next
  • An increase within the lowest 3 levels that crosses the midpoint of a level (e.g., bottom half of Basic to top half of Basic)
§6.3 · §6.8 — What Does NOT Count

No Growth / No Calculation

  • Any decrease in performance level = 0 (§6.3)
  • Students with no prior-year Mississippi score are excluded from growth entirely (§6.8) — this includes out-of-state transfers
  • Students taking the Alternate Assessment this year who took the general assessment last year (§6.14)
  • Students in the first tested grade have no baseline

📊 Business Rule §6.2 — Individual Student Growth Weights

Additional weight of 1.25 is applied in the numerator for individual students who demonstrate exceptional growth. This is a per-student calculation, not a school-level designation.

1.0
Standard: Meets growth criteria above
1.25
Enhanced: Stays at Advanced year-to-year
1.25
Enhanced: Increases 2+ proficiency levels
1.25
Enhanced: Reaches the highest proficiency level

Note: Although the 1.25 weight can increase the numerator, no accountability component may exceed its allocated maximum points (§6.2 note).

LP25% Subgroup Components (§7): The Lowest Performing 25% Student Subgroup is identified separately for Reading and Math at each school. These are the students whose prior-year standardized scores place them in the bottom 25% within each grade. Growth for this subgroup is calculated as a separate, dedicated component — this is why both models have a distinct "LP25% Subgroup" growth component in addition to the "All Students" growth component.

Business Rule §2 — Full Academic Year

Does Your Student's Score Count? Understanding FAY & Transfers

The Full Academic Year rule determines which students are included in accountability calculations. Per §2.1: enrollment is regardless of attendance — a student who is enrolled but absent still counts toward FAY days.

*Exact date published yearly by MDE. §2.1 Note: 74.5% will NOT be rounded up to 75%. §2.3: Weekends and holidays are included in the calculation.

§2.1 — The Core Rule: A student meets FAY when enrolled (regardless of attendance) for at least 75% of calendar days from September 1 through the first day of state testing. This date is published annually by MDE and is the same for all schools, students, and assessments. For 4×4 block-scheduled courses, FAY is calculated differently — see §2.2.

Key FAY Business Rules — Verified from Document

§2.1 — The 75% Rule

Enrollment, Not Attendance

Enrollment is measured regardless of attendance. A student who is enrolled but chronically absent still counts toward FAY calendar days. Days are calendar days — weekends and holidays count. 74.5% does NOT round up to 75%.

§2.2 — 4×4 Block Schedules

Different FAY Windows

For 4×4 block-scheduled courses, Fall semester FAY = Sept 1 → first day of Fall primary testing. Spring semester FAY = Feb 1 → first day of Spring testing. MDE publishes these dates annually.

§2.4 — Inter-School Transfer

Score Follows FAY School

If a student meets FAY at School A but is enrolled at School B at time of testing, the score is attributed to School A. The school where FAY was met receives the accountability impact — positive or negative.

§2.5 — No FAY Anywhere

Score Not Counted

If a student does not meet FAY at any school, that student's assessment score is excluded from all school accountability calculations for that year.

§2.6 — District-Level FAY

Within-District Combining

FAY is calculated at both the school and district level. A student who transfers within a district may meet FAY for the district (combined days) but not for either individual school. District scores are separate from school scores.

§2.7 — Same-Day Enrollment/Withdrawal

One Day Counted

If a student enrolls and withdraws from the same (or different) school on the same day, that student is counted as having been enrolled for one (1) calendar day at the receiving school.

§2.10 — Dropout & Re-Enrollment

FAY Clock Resets

If a student drops out and re-enrolls within the same school year, the re-entry date becomes the next enrollment date. Days accumulated before the dropout are not carried forward. The FAY calculation restarts.

§2.11 — Concurrent Enrollment

Counted at Both Locations

If a student has concurrent enrollment in more than one school or district, the period of concurrent enrollment is included in FAY calculations at both locations. This is a unique provision for dual-enrollment situations.

§6.8 — Growth Without Prior Score

Out-of-State Transfers

A student without a prior-year Mississippi assessment score is excluded from all growth calculations — including both the All Students and LP25% growth components. They may still count toward proficiency if FAY is met. There is no prior-state-score substitution.

Transfer Scenarios: Does the Score Count?

🌐 Scenario 1: Out-of-State Transfer

§2.1§6.8

A student moves from Alabama to Mississippi in October and enrolls at your school. They have never taken a Mississippi state assessment. MDE publishes the first-day-of-testing date annually — use your FAY calculator below to determine if enrollment by a specific date meets the 75% threshold.

Proficiency (§2.1): If the student is enrolled early enough to accumulate ≥75% of calendar days from Sept 1 to the first day of testing, their proficiency score COUNTS toward your school's Reading and Math Proficiency components.

Growth (§6.8): No Growth score can be calculated — ever — in the first year of enrollment. There is no prior-year Mississippi baseline. The student is excluded from ALL four growth components (Reading-All, Reading-LP25%, Math-All, Math-LP25%) in their first year. A prior-state score is not accepted as a substitute.

⚠️ Proficiency: Counts IF enrolled by FAY deadline. Growth: EXCLUDED in year of transfer — no exceptions. No out-of-state score substitution.

🏫 Scenario 2: In-State Transfer — Same District

§2.6§2.4§2.5

A student transfers in January from School A to School B within the same district. School A enrolled them Sept 1; School B enrolled them January 15. Assume the testing window opens April 15 (~226 calendar days from Sept 1).

School-Level FAY: School A had the student ~136 days (Sept 1–Jan 14). School B has them ~90 days (Jan 15–Apr 15). The 75% threshold for a 226-day window = 170 days. Neither school alone reaches 170 days. The student does NOT meet school-level FAY at either school.

District-Level FAY (§2.6): The district combines both schools' days: 136 + 90 = 226 days = 100% of the window. The student meets DISTRICT-level FAY and is included in the district's accountability data.

Score attribution (§2.4): Since the student met FAY at no individual school, the score is not attributed to either School A or School B for school-level accountability. It counts only at the district level.

⚠️ School Level: Score excluded at both schools individually. District Level: Score counts — combined days met district FAY. These are separate calculations (§2.6).

🏘️ Scenario 3: In-State Transfer — Different Districts

§2.4§2.5

A student was enrolled at School A (District 1) from September 1 through March 1 — approximately 181 calendar days of a 226-day window (80.1%). On March 2 they transfer to School B (District 2) and sit for the state exam there.

FAY determination: 181 ÷ 226 = 80.1% at School A. This exceeds the 75% threshold. FAY is met at School A.

Score attribution (§2.4): Even though the student physically tests at School B, the score is attributed to School A — the school where FAY was met. School A receives both the proficiency and growth accountability impact. School B does not receive this student's data.

✅ Score COUNTS — attributed to School A (where 75% FAY threshold was met). School B receives no data from this student. The student's growth score also goes to School A if they have a prior MS baseline.

📝 Scenario 4: Student Met FAY, Then Transferred Before Testing

§2.4

A student enrolled September 1 at School A and accumulated 75%+ of calendar days before the testing window — FAY is established. In March (before testing), they transfer to School B in a different district and sit for the test there.

FAY cannot be "un-met." Once the 75% threshold is reached, the accountability designation is locked in. The subsequent transfer does not change the FAY determination at School A.

Result (§2.4): The score goes back to School A regardless of where the student tests. School A retains accountability for this student's performance even after they have physically departed the school.

✅ Score COUNTS for School A. FAY is a threshold determination — once met, it cannot be reversed by a subsequent transfer. This is a critical point for principals managing mid-year withdrawals.

🔄 Scenario 5: Dropout and Re-Enrollment

§2.10

A student enrolled September 1 at School A, attended through November 30 (91 calendar days), then dropped out. They re-enrolled at School A on February 1 and remained through the testing window (assume April 15 = 73 days from Feb 1).

§2.10 — Clock Resets at Re-Entry: The 91 days before the dropout are forfeited. The FAY calculation begins from the re-enrollment date of February 1. Days accumulated = 73 days. Window = 226 days. Percentage = 73 ÷ 226 = 32.3%.

Result: FAY is NOT met. The student's score is excluded from School A's proficiency and growth data. This is a distinct outcome from a voluntary transfer — the dropout event itself resets the clock.

❌ Score does NOT count. Dropout resets the FAY enrollment clock per §2.10. Pre-dropout days cannot be combined with post-re-enrollment days. This differs from a transfer, where §2.4 applies.

Districts are calculated as one K–12 school (§1.5). District performance classification is separate from district accreditation status (§2.3).

⚠️ Participation Rate Override (§4.1): Even if a school earns enough raw points for a higher letter grade, failure to meet the 95% participation threshold results in an automatic drop of ONE full performance classification (letter grade). This override occurs before the final grade is assigned and cannot be appealed on participation grounds alone.
§1.1 — When Cut Scores Are Raised: MDE will increase the performance standards when student proficiency reaches 75% and/or when 65% of schools/districts earn a grade of B or higher. Cut scores are also reviewed following the implementation of any new assessment (§1.6).

Business Rules §9 · §25 · §26 — HS Model Only

How Is the Readiness Indicator Calculated?

The Readiness Indicator applies only to schools with 12th grade and is worth 150 total points — three sub-components of 50 points each. Each sub-component is scored as: numerator ÷ denominator × 50.

🚀 Acceleration (50 pts) · §9

Percentage of eligible students taking AND passing accelerated courses. Numerator = students taking & passing; Denominator = all students whose MSIS grade is 11th or 12th (§9.4.2). Score = (num ÷ den) × 50.

Qualifying Course/Credential
Advanced Placement (AP) — must score ≥3 on AP exam (§9.2)
International Baccalaureate (IB) — must score ≥4
AICE — must pass the exam
Dual Credit — grade of C or above (§9.2)
SBE-approved Industry Certification

🎯 Assessment (50 pts) · §25

Based on the ACT Superscore, ACT NCRC, SAT, or ASVAB scores at end of month 9. Each student receives a value between 0 and 1 per the table below. Denominator = all Senior Snapshot students (§25.5).

Senior Snapshot (§27): Senior Snapshot is a method for identifying which high school students are included in participation rate calculations and Readiness Indicator measures. It captures ALL students continuously enrolled in a Mississippi public school from month 1 of 10th grade through month 9 of 12th grade (or until a completion status is entered). Beginning 2025-2026, students with dropout status entered in month 9 of 11th grade or at any time in 12th grade are also included (§27.3). Senior Snapshot is NOT a separate scored component — it defines the population used in Readiness calculations.

Policy §3.4 · Business Rules §11 · §12 · §13

Which Schools Are Identified for Intervention?

Schools identified as At-Risk include those earning an F under state accountability AND those identified under federal ESSA requirements for CSI, TSI, or ATSI status.

Mississippi Accountability · §3.4

F-Rated School = School At-Risk

A school earning an F under the SBE accountability system is automatically designated a School At-Risk and in need of assistance per Miss. Code Ann. §§37-18-3 and 37-18-5. State intervention follows.

Federal ESSA · §11 · CSI

Comprehensive Support & Improvement

Method 1: Graduation rate ≤67% (3-year cycle). Method 2: Title IA school in bottom 5% of overall accountability index (3-year cycle). Method 3: Previously ATSI school failing to exit after 3 years with 3 consecutive years of subgroup scores at or below the bottom 5% of Title IA schools (§11.3).

Federal ESSA · §12 · TSI

Targeted Support & Improvement

A school with a subgroup composite score in the lowest 50% of overall accountability AND in the lowest quartile of 3-year average gap-to-goal AND in the lowest quartile of 3-year improvement toward gap-to-goal closure. Schools meeting all three criteria are rank-ordered; bottom 5% not already identified for CSI are identified for TSI (§12.2).

Federal ESSA · §13 · ATSI

Additional Targeted Support

A school where a subgroup's 3-year average performance is at or below the performance of all students in the lowest-performing 5% of Title IA schools statewide. Applies to any school — Title I or non-Title I. Identified on a 3-year cycle (§13.1).

District of Transformation (§2.9.3): The SBE may place a district into a District of Transformation — without a State of Emergency declaration — if: (1) the district receives an "F" designation for 2 of 3 consecutive years, (2) a school/district receives D or F for all 4 consecutive years, (3) more than 50% of schools are School At-Risk in any one year, or (4) the district faces a serious lack of financial resources. No prior CSA action or Governor action is required.
ASD Dissolved (Footnote 1, p. 17): Pursuant to Miss. Code Ann. §37-17-6.1, no local school district has been placed into the Mississippi Achievement School District since July 1, 2024, and the Mississippi Achievement School District was dissolved effective July 1, 2025. Schools previously in the ASD have returned to their home districts.

Policy §2.3 · §2.5 · §2.8 · §2.9

What Do District Accreditation Statuses Mean?

District accreditation is separate from school performance classifications. Districts are accredited based on compliance with Process Standards and Accreditation Policies — not solely on school grades.

✅ Accredited

Assigned to a district that complies with Accreditation Policies and 100% of Process Standards. Local board retains full governance authority. (See exceptions in Appendices F and H of the MDE document.)

⚠️ Accredited on Probation

Assigned when a district fails to comply with 100% of Accreditation Policies and Process Standards. The district must develop and implement a Corrective Action Plan (CAP) with defined timelines submitted within 60 calendar days of notification (§2.8.1).

🚨 Accreditation Withdrawn

Assigned to a district previously on Probation that failed to comply with its CAP within approved timelines — or placed in a District of Transformation. Status is listed as WITHDRAWN NOT ACCREDITED. District may petition for reinstatement on January 1 or July 1 (§2.8.2.5).

Immediate Downgrade Triggers (§2.5): Certain violations can immediately downgrade a district's accreditation status mid-year, including: reporting false information (§2.1), failure to comply with test security procedures (Standard 16), failure to comply with graduation requirements (Standard 14), and violations of Standards 29, 30, and 31 related to safe school climate.
