The top reported proficiency rate is 27% in English language arts. The lowest is 15% in Science.
Original Research by School Decision on Diekman Elem School
Diekman Elem School serves prekindergarten through sixth grade in Dolton, a working-class suburb roughly 20 miles south of Chicago that has experienced sustained population decline and economic strain over recent decades following the loss of its industrial base. The school enrolls a small community of students, roughly the size typical for a neighborhood elementary school in this setting, with an enrollment heavily concentrated in the early grades, particularly in preK.
The student body is overwhelmingly Black, reflecting the neighborhood's composition. Race and ethnicity data show the vast majority of enrolled students are Black, with a very small representation of other racial and ethnic groups. Free-or-reduced-price-lunch eligibility data was not available, so parents cannot see what share of the student population qualifies for meal assistance based on household income. Similarly, data on students with individualized education plans (IEPs) and English learners was not reported, leaving a gap in understanding student support populations.
State testing results from 2024-2025 show performance that is substantially below the midpoint among Cook County districts. In English language arts, third graders achieved proficiency at a low level, while fourth graders performed only modestly better. Fifth grade represents the school's strongest showing in ELA, with roughly half of tested students meeting proficiency. Math results are weaker: third grade sits below one-third proficiency, and fourth and fifth grades both dip to single-digit proficiency rates. Science testing in fifth grade, the only grade where science is assessed, shows proficiency below one-fifth. It is worth noting that state scoring criteria shifted in the 2024-2025 year, so year-over-year comparison is not reliable; parents may want to discuss with the school how recent results fit into a longer-term trajectory.
Testing participation rates were consistently high, near or at full participation where data was reported, indicating students took the assessments. Data for sixth graders was not provided, which likely reflects the district's recent reorganization that moved sixth grade from the elementary level to the middle school beginning in 2024-2025. This structural change means Diekman is no longer a traditional K-6 building.
The district has introduced a Career and Technical Education (CTE) program at the middle school level that expanded in recent years to include pathways in skilled trades, cosmetology, barbering, and other vocational areas. Since Diekman no longer houses sixth graders, parents whose children would have entered the CTE program would find it in the middle school rather than in this building.
The Dolton area itself reflects decades of post-industrial adjustment. The village is a car-oriented, brick-house suburb with commercial activity concentrated along highways rather than a walkable center, and it has seen significant fiscal challenges including bond defaults. Housing values in the area are modest relative to the broader Cook County market. There is no indication of major new housing or development in Dolton itself beyond the village's recent acquisition and planned renovation of a historic landmark home.
Diekman is open and operational and serves its immediate neighborhood. Parents considering it should understand that state assessment results show material academic performance gaps relative to other elementary schools in the county, and they would benefit from a direct conversation with the school about instructional approaches, additional support services, and any tailored interventions for students who are not yet proficient.
