/ Student Success Capacity Index

The SSCI scores
your institution's
capacity to complete
every student it admits.

A 147-item psychometric instrument that audits institutional systems — budget allocations, staffing authority, governance design, policy architecture, and disaggregated outcome data. Built from peer-reviewed research, validated at national scale, and calibrated against 2,595 IPEDS-reporting institutions.

§ 01   The Instrument
01

A diagnostic that names the structural lever, not just the outcome gap.

About the name: The Student Success Capacity Index (SSCI) is Atlas & Crown's applied institutional diagnostic, built on the Equity Infrastructure Index (EII) — a peer-reviewed formative composite developed to measure how institutional systems are structured to produce student success outcomes. The EII is the scholarly instrument; the SSCI is what institutions engage with commercially.

Every institutional leader knows the gap. Completion lags for lower-income students. Retention differentials persist after the first year. Transfer outcomes diverge by income and first-generation status. The data is on dashboards across the country.

What's missing is the mechanism — the specific arrangement of budget authority, staffing depth, governance design, and policy ownership that determines whether the institution is built to close the gap or simply to report it.

The SSCI does not measure intentions. It measures whether the institution's systems are built to produce the outcomes it claims to want.

A score of 67 with a 14-point completion differential and a structural authority sub-score of 32 tells a leader exactly which governance lever to pull first — and what the projected return on that structural investment is at p < .001.


§ 02   What it measures

Six predictor domains. One scored architecture.

The SSCI is a formative composite: each domain is empirically distinct, federally observable via IPEDS for Layer 1, and audited at internal granularity in Layer 2. Outcomes are the dependent variable, not a weighted input.

Domain What is measured Layer 1 source
Structural Authority The reporting line, budget authority, and decision rights of student success leadership. The variable with the largest pre-validation effect size. IPEDS HR; org. disclosures
Financial Architecture Per-student investment in academic and student support — disaggregated, FTE-corrected, and benchmarked against true Carnegie peer institutions. IPEDS F1A / F2
Staffing & Caseload Advising ratios, coaching capacity, and staff representation calibrated against enrollment and Carnegie peer group. IPEDS HR
Policy & Governance The codified governance architecture for escalation, exception, policy ownership, and remediation. Distinguishes institutions where completion policy has an accountable owner from those where responsibility is ambient. Public catalog audit
Net Price & Access What the lowest-income quintile actually pays, compared to peer institutions with similar Pell concentrations. IPEDS SFA
Completion & Retention Architecture Retention, graduation, and completion by Pell status, income quartile, transfer status, and time-to-degree — the outcome column the prior domains predict. IPEDS GR / Outcomes
§ 03   Architecture

Two layers. Pre-call benchmarked. Post-call validated.

On validation: Layer 1 has pre-validation evidence from national IPEDS data across 2,595 institutions, significant at p < .001 across five completion outcomes. Layer 2 validation — confirmatory factor analysis and MIMIC modeling — is underway with the founding cohort. These are sequential and complementary, not contradictory.

Layer 1 · Pseudo-SSCI

Built from public data

Every IPEDS-reporting institution receives a Layer 1 score from federally mandated public data — no institutional cooperation required, no selection bias. Every prospect benchmarked before the first call.

Layer 2 · Internal SSCI

Audited from inside

The full 147-item instrument administered with institutional cooperation. Captures policy and governance variables not visible in IPEDS; delivers the written strategic priorities memo with named levers. Phase 2 CFA underway with founding cohort.

The two-layer architecture is the trust architecture. Layer 1 proves the methodology before the conversation begins. Layer 2 produces the action plan after it. Convergent validity across two independent datasets at two levels of analysis is the moat.

§ 06   Methodology lineage

Where the instrument comes from.

The SSCI is the commercial application of the Equity Infrastructure Index (EII), built from Dr. Staples's published research on institutional investment, unit power, and student success outcomes. The empirical foundation is established at two levels:

i.

Dissertation research (UGA, 2025). Established at the state Multicultural Student Programs & Services unit level that structural authority and per-student investment predict retention for students of color using QuantCrit methodology.

ii.

National IPEDS replication (2026). Confirmed the dissertation findings at full national scale with observed census data across 2,595 institutions — five validated outcomes, all significant at p < .001.

iii.

Phase 2 validation (underway). Confirmatory factor analysis and MIMIC modeling with founding cohort institutions. McDonald's omega designated for reliability estimation; Cronbach's alpha is explicitly rejected for this formative composite.
