Accessible Portable Item Protocol™ (APIP™)


The Accessible Portable Item Protocol (APIP) Standard provides assessment programs and question item developers with a data model for standardizing the interchange file format for digital test items. When applied properly, the APIP standard accomplishes two important goals. First, the standard allows digital Tests and Items to be ported across APIP compliant test item banks. Second, it provides a test delivery interface with all the information and resources required to make a Test and an Item accessible for students with a variety of disabilities and special needs. Read the APIP Frequently Asked Questions.

APIP Version 1.0 focuses is on:

  • Enabling the exchange of question Items and Tests;
  • Adopting, wherever possible, established learning technology interoperability standards and specifications, and only extending these when required;
  • Ensuring that the solution can be readily expanded, at a later date, to support the exchange of other related assessment information;
  • Ensuring the solution can be combined with other IMS and non-IMS specifications to support new functionality, e.g., the reporting of assessment scores and outcomes;
  • Ensuring that further profiling can be undertaken to tailor the approach to meet the needs of specific state assessment activities without compromising the baseline interoperability requirement and capability;
  • Enabling vendors to adopt the solution without constraining their ability to create market-differentiated products and services.
APIP basic flow

APIP is based on the IMS Question and Test Interoperability™ (QTI) specification. The APIP Standard expands the QTI model into a comprehensive framework that encompasses the requirements for creating accessible tests. The IMS Access For All Personal Needs & Preferences (AfA PNP) v2.0 specification is also adopted as the basis for supplying the user preferences when using an APIP-enabled system. It is these accessibility preferences that are used by an assessment system to tailor, in real-time, the presentation of the question items to fit the accessibility needs of the user.

 

Conformance

A conformance certification program and online validation tool have also been developed and deployed. The IMS QTI/APIP Accredited Profile Management Group (APMG) maintains the QTI and APIP conformance tests. While conformance certification provides a "seal" for passing prescribed tests it is much more than that. It is a commitment by a supplier to the IMS community for ongoing support for achieving "plug and play" integration. Therefore, certification implies ongoing community commitment to resolve problems, revise implementations and retest as need. Therefore, only IMS Contributing Members, Affiliate Members and QTI/APIP Alliance participants are eligible to apply for conformance certification.

Organizations procuring QTI or APIP products are strongly encouraged to require IMS conformance certification for all such products to ensure the highest levels of interoperability are achieved across the educational community. Products that have achieved conformance certification are listed and updated at imscert.org.

The following document is a primer on conformance and the relationship between QTIv2.x and APIP. It is highly recommended that this document be read prior to reading the other specifications:

APIP Simplified Conformance

 

Version 1.0 Final Specification

The APIP v1.0 Final specification was approved by the IMS Technical Advisory Board in May 2014. This replaces the 2012 Candidate Final specification and includes minor additions that are elective/optional in terms of conformance. A further update to include these corresponding changes in the base QTI specification will result in a QTI v2.2 update that will be available as a public draft later this year. IMS strongly encourages suppliers to certify their content and systems against one of the available conformance profiles, details in the Alliance. To see a list of current APIP or QTI certified products, check out imscert.org.

The QTI/APIP APMG welcomes feedback and advice from the community for the improvement of these standards at the APIP Public Forum.

Version 1.0 XSDs and Namspaces:

This is the set of Final Release XSDs developed by IMS Global to support validation of instances that conform to the APIP Entry and Core Profiles. The namespace and schema location details for the APIP Profiles XSDs are provided in the tables below.

  1. Entry Profile XSDs - the XSDs for the APIP Entry Profile;
    1. Packaging XSDs - the XSDs for the APIP Package in the Entry Profile;
    2. PNP XSDs - the XSDs for the APIP PNP instance in the Entry Profile;
  2. Core Profile XSDs - the XSDs for the APIP Core Profile;
    1. Packaging XSDs - the XSDs for the APIP Package in the Core Profile;
    2. PNP XSDs - the XSDs for the APIP PNP instance in the Core Profile;

The key for the tables is:

  • "Namespace" - the namespace for the XSD (must be supplied in any XML instance referring to the corresponding XSD);
  • "XSD File Name" - the filename for the XSD;
  • "Schema Location" - the schema location for the XSD (must be supplied in any XML instance referring to the corresponding XSD);
  • '*' denotes that all of the files are held in the directory located at: "http://www.imsglobal.org/profile/apip/apipv1p0/entry";
  • '**' denotes that all of the files are held in the directory located at: "http://www.imsglobal.org/profile/apip/apipv1p0/".
