Muthen & Muthen Accessibility Statement
Mplus Version 8.6 and Selected Pages from User’s Guide
(Based on VPAT ® Version 2.4)
The Section 508 of the Rehabilitation Act of 1973, as amended by Congress in the Workforce Investment Act of 1998, and as revised in 2018, requires that electronic and information technology used by Federal agencies be accessible to people with disabilities.
This page provides information about Muthen & Muthen's Section 508 compliance, including Voluntary Product Accessibility Template (VPAT) documenting compliance.
Conformance status

Mplus v.8.6 and its associated PDF user guide is partially conformant with WCAG 2.0 level AA. Partially conformant means that some parts of the content do not fully conform to the accessibility standard.
Compatibility with browsers and assistive technology
Mplus v.8.6 is designed to be compatible with the following assistive technologies:
- Partial support for JAWS and NVDA on Windows 10
- Partial support for Adobe Acrobat Pro DC on Windows 10
