Data snapshot Updated

Azimuth ranks Southern Illinois University-Carbondale #243 nationally among nonprofit four-year institutions.

Who it’s a good fit for

Southern Illinois University-Carbondale is a public university in Carbondale, Illinois, with a degree mix led by Education, Business, and Engineering Technologies. Mobility is its strongest , at well above average.

Graduates out-earn what predicts for students like them. The model attributes part of that to the factors it measures, which add, and part to what it cannot explain, which subtracts.

Return is above average, the weakest of the four pillars. What families pay after aid stretches across a wide range: the lowest income band averages well below the published cost, while the highest band pays closer to it.

Pell students complete at a rate that trails the overall cohort, and mobility is well above average. The admission rate is near the median for comparable schools, and most graduates are estimated to go into work rather than further study.

A student drawn to the largest programs should know that the best-paid ones are much smaller.

SIU rankings: how Azimuth assesses value[5]

Southern Illinois University-Carbondale enrolls 8,494 undergraduates at a public university in Carbondale, Illinois. Among nonprofit four-year institutions, the university falls in the top third (83rd percentile).

Southern Illinois University-Carbondale admits 86.9% of applicants, while the peer median—the middle value for comparable institutions (same type and size)—is 85.9%. Full-time first-year students return at a rate of 66.8%, against a peer median of 73.7%.

The six-year graduation rate for the first-time full-time cohort is 62.4%, while the peer median for comparable institutions (same type and size) is 49.1%. Because that rate counts only first-time, full-time students, it describes a minority of the people who study here; an estimated 42.4% of undergraduates arrive as transfers or part-time students.

The four pillars stretch across a wide band, with mobility the strongest (88th percentile) and return the weakest (55th percentile). Access and affordability sit between them (75th and 79th percentiles), so no single pillar dominates the profile.

Azimuth ranks Southern Illinois University-Carbondale #243 among 1,467 nonprofit four-year institutions, with mobility as the strongest pillar in the 88th percentile. Affordability follows in the 79th percentile, and access sits in the 75th percentile.

The return pillar is the weakest, in the 55th percentile, though all four pillars land above the median for nonprofit four-year institutions.

The middle 50% of submitted SAT scores at Southern Illinois University-Carbondale fell between 900 and 1,160. For students who submitted ACT scores, the middle 50% ranged from 18 to 25.

38.8% of undergraduates receive Pell Grants, a measure of financial access at this public university in Carbondale, Illinois. Azimuth ranks the university #372 for access among nonprofit four-year institutions.

Pell Grant recipients complete at a rate of 48.5%, which sits 13.9 percentage points below the overall six-year graduation rate. The gap is a direct measure of how outcomes for these students compare to the entering cohort as a whole.

Mobility is the strongest pillar here, with Azimuth ranking Southern Illinois University-Carbondale #176 for mobility. Graduates earn about $2,808 more than the model expects for similar students, a result that coincides with the university's high mobility standing.

SIU career outcomes & earnings[3][8][9]

Graduates of Southern Illinois University-Carbondale earn about $2,808 more than the model expects for similar students, a result in the 65th percentile among nonprofit four-year institutions. The part the model attributes to the factors it measures (field of study, enrollment and the local labor market) adds $5,934.

The part it attributes to a remainder it does not explain subtracts $3,126. Within the measured factors, the STEM component adds $1,734.

Four years after completion, completers earn a median of $61,484, which is above the peer median of $57,301 among comparable institutions (same type and size) by $4,183. The median sits in the 55th percentile nationally.

Azimuth places the return pillar in the 55th percentile. The earnings picture is mixed: graduates beat the model's expectation, but the institution's own contribution subtracts from that advantage, leaving the overall return pillar near the middle of the pack.

Federally aided graduates of Southern Illinois University-Carbondale who are working and not enrolled earn a median of $61,484 four years after completing a degree. That median is $4,183 above the $57,301 figure for comparable institutions (same type and size).

The earnings cohort includes 3,807 completers. The median sits in the 55th percentile among nonprofit four-year institutions.

Graduates earn about $2,808 more than the model expects for similar students. That gap falls in the 65th percentile among nonprofit four-year institutions.

Earnings scenarios estimated from the program mix span from $44,965 on the downside to $85,380 on the upside, with a typical outcome of $61,484. An estimated 25.4% of graduates continue to graduate study, based on the program mix.

Four years after completing a degree, federally aided graduates of Southern Illinois University-Carbondale who are working and not enrolled earn a median of $61,484, at the 55th percentile. That is $4,183 above the $57,301 median for comparable institutions (same type and size).

Graduates earn about $2,808 more than the model expects for similar students, placing that gap at the 65th percentile. Earnings scenarios grounded in the university's program mix show a downside of $44,965 and an upside of $85,380, with the typical scenario at $61,484.

Azimuth ranks the university #657 for return among nonprofit four-year institutions. Of the earnings beyond expectations, the model attributes $5,934 to the factors it measures, a share that adds to expected earnings.

It attributes $3,126 to a remainder it does not explain, which subtracts. Within the measured factors, the STEM component adds $1,734.

The university's program mix leans toward technical and applied fields. An estimated 25.4% of graduates continue to graduate study, a figure estimated from the program mix rather than observed enrollment.

The earnings scenarios point to a wide spread: the downside scenario is $44,965 while the upside scenario reaches $85,380. These are scenarios estimated from the program mix, not observed groups of graduates.

At the higher end, Fire Protection graduates earn $108,135 four years after completion, from 36 degrees awarded. Computer Science follows at $91,299, and Industrial Production Technologies/Technicians at $87,442.

Graduates of Southern Illinois University-Carbondale earn about $2,808 more than the model expects for similar students. The median federal student debt for borrowers who complete a degree is $21,543, which runs above the median of $21,229 for comparable institutions (same type and size).

If repaid over ten years, that debt would mean a monthly payment of $245. The average net price for aid recipients—what they pay after grants and scholarships—is $13,297, which is below the peer median of $14,068.

Parent PLUS borrowers, a separate population, carry a median of $19,500. A low average net price and earnings that exceed the model's expectation point the same way for a student who finishes. The debt figure is close to the peer median.

Data scope & methodology

Structured payloads generated Governed hub narrative Governed spoke corpus

Four-year earnings describe cohorts of completers. Figures for other horizons describe different cohorts and are not joined into a career-growth projection.

Azimuth's overall rank and pillar percentiles come from the school profile. Absolute pillar ranks, city, enrollment and official-site links are shown only when structured data supplies them.

Detailed earnings, cost, admissions and program values come from the endpoint responsible for each measure. Missing values are not replaced with zero. Value-added estimates are model associations, not causal effects.

Figures are refreshed with each data release, at most a quarter apart. The underlying source dates can be earlier than the release.

Explanatory text is AI-assisted drafting checked against those figures; it is not an additional data source.
