7.5 Historical and Philosophical Foundations and Current Trends

From Exclusion to Entitlement

The Sequence

Special education's history is a sequence of moves in one direction, and knowing the order is more useful than knowing every date.

The distinction the exam tests is mainstreaming versus inclusion. In mainstreaming, the student must earn placement by fitting the existing classroom; the burden of adaptation is on the student. In inclusion, the student belongs there by default and the classroom adapts; the burden is on the system. UDL, co-teaching, and supplementary aids and services are the machinery of the second.

The Cases That Forced the Change

• Brown v. Board of Education (1954) — held that separate is inherently unequal. Though a race case, its equal-protection reasoning became the foundation of every disability-rights education case that followed.
• PARC v. Commonwealth of Pennsylvania (1972) — consent decree establishing that children with intellectual disabilities are capable of benefiting from education and are entitled to free public education.
• Mills v. Board of Education of the District of Columbia (1972) — extended PARC to all disabilities and rejected insufficient funds as a defense for exclusion.

The Legislative Sequence

Two features of PL 94-142 are worth remembering as landmarks: it was the first law to make education an entitlement rather than a privilege for children with disabilities, and it built enforcement into the statute through procedural safeguards that parents themselves could invoke.

Philosophical Foundations and Current Trends

Normalization and Least Restrictive Environment

Normalization (Bengt Nirje, Wolf Wolfensberger) held that people with disabilities should have access to the ordinary patterns and conditions of everyday life — the same daily rhythm, the same life cycle, the same economic and community standards as everyone else. It drove deinstitutionalization and is the philosophical ancestor of both the least restrictive environment mandate and community-based instruction. Social role valorization, Wolfensberger's later formulation, added that services should help people occupy socially valued roles — employee, neighbor, student, friend — rather than merely be present in ordinary settings.

Medical and Social Models

The medical model locates disability inside the individual and directs attention to diagnosis and remediation. It produced the eligibility categories special education depends on and much of the intervention research, and its risk is a deficit orientation that treats the student as the problem. The social model locates disability in the interaction between an impairment and an environment that was not designed for the person, and directs attention to barrier removal. It produced accessibility law, universal design, and the self-advocacy movement, and its risk is understating the genuine need for specialized instruction.

Competent practice uses both: teach the student to decode and provide the audio text; build communication skills and ensure every partner knows how to use the system. The neurodiversity and disability-culture perspectives extend the social model by treating some differences as identity rather than pathology, which is why language preference should follow the individual and family.

Current Trends Named in the Framework

Objective 0012 names four explicitly.

1. Advances in technology. Speech-generating devices and eye-gaze access, speech-to-text and text-to-speech now built into standard operating systems, digital progress-monitoring and data systems, telepractice for related services in areas with provider shortages, and remote interpretation. Two cautions travel with this trend: accessibility of digital materials is a legal obligation under Title II, and technology is a support for instruction rather than a substitute for it.
2. Inclusive practices. Co-teaching, UDL, high-leverage practices, standards-aligned IEPs, and the reduction of separate settings, alongside inclusive postsecondary education programs for students with intellectual disabilities.
3. Early intervention. Part C, developmental screening, and evidence that the earlier the support the better the trajectory; the associated policy trend is toward coaching families in natural environments rather than clinic-based child-only therapy.
4. Multi-tiered systems of support. MTSS integrating academic and behavioral support with universal screening and data-based decision making, permitted for SLD identification since IDEA 2004 and required in Illinois as part of the SLD evaluation process.

Other Trends Worth Knowing

• Disproportionality monitoring and the required reservation of funds for coordinated early intervening services.
• Restraint and seclusion reduction, including Illinois's statutory goal of reducing and eventually eliminating time out and physical restraint.
• Trauma-informed and mental health-integrated practice, reflected in Illinois's mental health and SEL requirements.
• Evidence-based practice and high-leverage practices, with CEC and federal clearinghouses defining what qualifies.
• Personnel shortages, which shape practical questions about caseloads, service delivery models, and the use of paraprofessionals.

Persistent Tensions

The field's open questions are worth being able to state plainly, because scenario items are often built on them: full inclusion versus a genuine continuum of placements; identification accuracy versus the harms of both over- and under-identification; standardized accountability versus individualized programming; and the gap between what IDEA promised in funding and what Congress has actually appropriated, which shapes every district's capacity.
