District Size and Staffing
Oak Grove SD 68 Green Oaks operates with a lean instructional footprint. According to Illinois State Board of Education enrollment and staffing data (2024–25), the district employs 76 teachers on a full-time basis, with no reported FTE variance. This staffing level reflects a student-to-teacher ratio consistent with suburban Illinois norms.
The teaching force is differentiated by role and specialization. The majority—63 full-time positions—are classified as general classroom teachers.

Compensation Structure and Salary Baselines
Salary Schedule
The Illinois State Board of Education Temporary Salary Schedule (ISBE TSS) for 2025–26 provides the district's official salary framework. Oak Grove SD 68 Green Oaks uses a traditional lane-and-step progression model based on degree attainment and years of service.
BA-degree track: Beginning salary of $48,778, reaching a maximum of $74,169 after 18 years of service.
MA-degree track: Starting at $58,095, with a maximum of $88,339 after 18 years—a cumulative gain of approximately $30,244 over the bachelor's-level ceiling.
MA+30-degree track: Entry at $69,192, culminating at $105,209 after 18 years of service, the single highest step in the published schedule.
A Master's-degreed teacher at the 10th-year step earned $72,502 according to the TSS 2025–26 baseline. These figures establish the contractual framework; actual compensation varies based on individual credentials, service longevity, and any longevity or supplemental pay provisions extracted from the collective-bargaining agreement (CBA).
Actual Teacher Compensation (2024–25)
Illinois EIS (Education Information System) 2024–25 data shows that actual teacher compensation in Oak Grove SD 68 Green Oaks exceeded published salary-schedule minimums:
- Average teacher salary: $89,628
- Median teacher salary: $89,244
- 25th–75th percentile range: $70,440 to $107,013
Among classroom teachers (n=63), the average was $87,949 with a median of $85,232. This distribution suggests a mix of early-career and experienced educators. Special-education teachers averaged $95,881 (median $96,902), exceeding general-education pay—a common pattern reflecting special-education staffing challenges and credential premiums. ESL teachers averaged $85,031.
The 25th-percentile figure of $70,440 aligns with the MA-track beginning salary plus modest step progression, indicating that approximately one-quarter of teachers earn near-entry compensation. The 75th-percentile threshold of $107,013 approaches or exceeds the MA+30 schedule maximum, reflecting experienced educators and longevity-based pay.
Benefits and Insurance
Benefits baseline data from ISBE TSS 2025–26 reveal Oak Grove SD 68 Green Oaks' approach to employee benefits design:
Health, Dental, and Vision Insurance
Health insurance carries the highest employer cost. Employee-only coverage costs $2,514 annually, with the district paying 83% ($2,086). Family health coverage is priced at $11,427, with a 77% employer contribution ($8,798). These rates are typical for Illinois school districts and reflect shared cost-responsibility between employer and employee.
Dental and vision coverage are fully employee-funded. Dental premiums are $532 (individual) and $2,053 (family). Vision insurance costs $114 (individual) and $334 (family). The absence of employer contribution for dental and vision is less common in larger Illinois districts but reflects cost-control measures in smaller systems.
Life and Disability Insurance
The district funds life insurance entirely; the annual employee premium is $39, fully employer-paid. Disability insurance similarly carries a $40 annual cost, borne entirely by the district. These are standard ancillary benefits with modest per-employee cost.
Leave Provisions
Oak Grove SD 68 Green Oaks provides 3 personal days annually. The district maintains a sick-leave bank (indicating that unused sick leave accumulates), though the maximum bank balance is not specified in the available source material. No early-retirement program or formal severance-pay schedule is documented.
Longevity Pay
Longevity compensation (supplemental pay for service milestones) is capped at:
- MA-degreed teachers: $100,025 maximum
- MA+30-degreed teachers: $157,158 maximum
These represent significant cumulative additions to base salary, particularly for veteran educators with advanced degrees, and may account for the observed spread between salary-schedule maximums and actual 75th-percentile compensation.
Retirement
The district pays 0% of Teachers' Retirement System (TRS) contributions; educators bear the full statutory employee contribution. TRS is not embedded in the published salary schedule, meaning salary figures represent cash compensation exclusive of pension-contribution mechanics.
Settlement History and Wage Growth
Oak Grove SD 68 Green Oaks has achieved consecutive annual agreements with its teacher bargaining unit over a decade. All documented settlements involve a single unit—Teachers—with no separate agreements for administrators, support staff, or other employee classes visible in the source data.

2022–23–2023–24: 3.00% Year 1, 3.00% Year 2
2021–22–2022–23: 3.00% Year 1, 3.00% Year 2
2020–21–2021–22: 2.75% Year 1, 2.75% Year 2
2019–20–2020–21: 5.00% Year 1, 7.34% Year 2

2015–16–2016–17: 1.45% Year 1, 1.45% Year 2
The pattern reflects three distinct eras:
- 2015–2018: Minimal growth (1.28%–1.45% annually), consistent with post-financial-crisis constraint and Illinois pension-funding pressures.
- 2019–2021: Acceleration, with the 2019–20–2020–21 agreement reaching 5.00% / 7.34%—likely reflecting improved state revenue and pandemic-era negotiating leverage.
- 2021–present: Stabilization at 3.00% annually, representing a compromise between district fiscal capacity and continued real-wage growth above inflation.
The current 3.00% baseline increase for 2024–25 is the latest documented year-1 figure and applies to all steps on the salary schedule. Two-year agreements predominate, suggesting predictable labor relations and multi-year budgeting stability.
