1. Introduction

1.1. Overview of the Service

The Competencies and Academic Standards Exchange (CASE) Service specification is the definition of how systems achieve the exchange of information about learning standards and/or competencies. The key aim is to replace the current ways of documenting a learning standard and competency, typically a PDF or HTML document, by one which is machine readable both syntactically and semantically. Further, using this new specification it will be possible to electronically exchange these definitions so that applications, systems and tools can readily access this data.

1.2. Scope and Context

This document is the Competencies and Academic Standards Exchange (CASE) Service Model v1.0 and as such it is used as the basis for the development of the following documents:

This information model defines the CASE Abstract Application Programming Interface (a-API). This service model is described using the Unified Modeling Language (UML) based upon the IMS Global Model Driven Specification approach and the associated modelling toolkit [I-BAT, 06]. This means that this specification is based upon the concepts of:

2. The Use-cases

The set of uses cases that can be supported by the usage of the CASE service are:

2.1. Use-case 1 (Obtaining the Definition of the Academic Standards/Competencies/Rubrics for a Module, Course or Programme)

Table 2.1 Obtaining the definition of the academic standards/competencies/rubrics for a module, course or programme usecase.
Title:	Obtaining the Definition of the Academic Standards/Competencies/Rubrics for a Module, Course or Programme
Local ID:	CASE-01
Description:	A teacher wishes to obtain the definition of a competency/academic standard for a key learning structure e.g. a course, a programme, etc. A detailed example is that a teacher needs to review the definition for a subject e.g. Year 11 French. Therefore the institutions's LMS must have obtained this breakdown for the corresponding District Learning Standards definitions repository. The teacher can then review the subject definition through the institution's LMS.
Level	Summary
Actors:	Primary - Learning Management System (Institution) and Competency/Academic Standard Repository (District) Secondary - Teacher
Stakeholder:	Teaching Institution e.g. School
Interest:	It is essential that the set of competency/academic standard definitions for the education to be supplied and against which the student will be measured are available electronically and installed in the institition's Learning Management System (LMS).
Notes:	In terms of the CASE specification, the LMS must have obtained the appropriate CFDocument description(s). The teacher does not need to be aware of how the LMS has obtained the definitions, merely that they are available and assured that they are consistent with the definitions supplied by the District.

2.2. Use-case 2 (Obtaining an Academic Standard or Competency Definition)

Table 2.2 Obtaining an academic standard or competency definition usecase.
Title:	Obtaining an Academic Standard or Competency Definition
Local ID:	CASE-02
Description:	A teacher wishes to obtain the detailed statements for a competency/academic standard for a key learning structure e.g. a course. A detailed example is that a teacher needs to understand the specific learning objectives that must be achived for a subject e.g. Year 10 Biology - The Carbon Cycle. Therefore the institutions's LMS must have obtained these statements from the corresponding District Learning Standards definitions repository. The teacher can then review the subject statements through the institution's LMS.
Level	Summary
Actors:	Primary - Learning Management System (Institution) and Competency/Academic Standard Repository (District) Secondary - Teacher
Stakeholder:	Teaching Institution e.g. School
Interest:	It is essential that the set of competency/academic standard statements for the education to be supplied and against which the student will be measured are available electronically and installed in the institition's Learning Management System (LMS).
Notes:	In terms of the CASE specification, the LMS must have obtained the appropriate CFItem descriptions. The teacher does not need to be aware of how the LMS has obtained the definitions, merely that they are available and assured that they are consistent with the definitions supplied by the District.

2.3. Use-case 3 (Obtaining a Rubric Definition)

Table 2.3 Obtaining a rubric definition usecase.
Title:	Obtaining a Rubric Definition
Local ID:	CASE-03
Description:	A faculty member wishes to obtain the rubrics which define the assessment marking schemes to be applied to the set of learning activities they are teaching. A detailed example is that the faculty member needs to read the marking scheme required for marking an essay on the use of resonance in electrical circuits. Therefore the institutions's LMS must have obtained these rubrics from the Institutions content repository that is used to store the rubrics (the rubric may have been created by a separate curriculum development team). The faculty member can then review the rubrics through the institution's LMS.
Level	Summary
Actors:	Primary - Learning Management System (Institution) and Rubrics Repository (Institution) Secondary - Faculty Member
Stakeholder:	Higher Education Institution e.g. University
Interest:	It is essential that the set of rubrics for the assessment of the various learning activities are available electronically and installed in the institition's Learning Management System (LMS).
Notes:	In terms of the CASE specification, the LMS must have obtained the appropriate CFRubric description (this will include the associated CFRubricCriteria and CFRubricCriterionLevels descriptions).

2.4. Use-case 4 (Obtaining the Associations between Academic Standards/Competency/Rubric Definitions)

Table 2.4 Obtaining the associations between academic standards/competency/rubric definitions usecase.
Title:	Obtaining the Associations between Academic Standards/Competency/Rubric Definitions
Local ID:	CASE-04
Description:	A Learning Management System (LMS) is responsible for displaying to a teacher the set of competencies/academic standards that are addressed by learning materials. The content is annotated with the competencies/academic standards from more than one source. A mapping between these competencies/academic standards from the different sources can be used to vary the information displayed. The mapping between the sources can supplied as a set of associations which must be supplied by one or other of the sources.
Level	Summary
Actors:	Primary - Learning Management System (Institution) and Competency/Academic Standard Repositories (Districts) Secondary - Teacher
Stakeholder:	Teaching Institution e.g. School
Interest:	Different organizations have preferred ways to compose a competency/academic standard. Suppliers of content want to annotate their materials to cover as wide a range of competencies/academic standards as possible. Therefore, a cross-walk between those different competency/academic standards is essential to understand their equivalence.
Notes:	In terms of the CASE specification, the LMS must have obtained the mappings using the appropriate CFAssociations structures. Once these associations have been supplied the LMS can use the cross-walk to display the competencies/academic standards in the structure preferred by the user.

2.5. Use-case 5 (Obtaining All of the Detailed Definitions of the Academic Standards/Competencies/Rubrics for a Module, Course or Programme)

Table 2.5 Obtaining all of the detailed definitions of the academic standards/competencies/rubrics for a module, course or programme usecase.
Title:	Obtaining All of the Detailed Definitions of the Academic Standards/Competencies/Rubrics for a Module, Course or Programme
Local ID:	CASE-05
Description:	A teacher wishes to obtain all of the information for a competency/academic standard for a key learning structure e.g. a course, a programme, etc. A detailed example is that a teacher needs to use all of the information (this includes all of the statements, the licenses, the rubrics, etc.) for the definition for a subject e.g. Year 11 French. Therefore the institutions's LMS must have obtained this breakdown from the corresponding District Learning Standards definitions repository. The teacher can then review the subject definition information through the institution's LMS.
Level	Summary
Actors:	Primary - Learning Management System (Institution) and Competency/Academic Standard Repository (District) Secondary - Teacher
Stakeholder:	Teaching Institution e.g. School
Interest:	It is essential that all of the information for the competency/academic standard definitions for the education to be supplied and against which the student will be measured are available electronically and installed in the institition's Learning Management System (LMS).
Notes:	In terms of the CASE specification, the LMS must have obtained the appropriate CFPackage structures. The CFPackage is a container for the CFDocument, the set of CFItems, the CFAssociations, the CFRubrics and the set of structural definitions i.e. the CFConcepts, the CFSubjects, the CFAssociationGroupings, the CFItemTypes and the CFLicenses. The teacher does not need to be aware of how the LMS has obtained the definitions, merely that they are available and assured that they are consistent with the definitions supplied by the District.

3. The Conceptual Model

3.1. The Information to be Exchanged

The CASE Service specification is the definition of how systems achieve the exchange of information about learning standards and/or competencies. Analysis of the underlying structure of both a competency and an academic standard determined that information constructs could be represented using the same data model. This enables the use of a single interoperability data model, which is composed of three core constructs:

The composition and logical structure of a competency/academic standard is shown in Figure 3.1. The document is the container for the set of competency/academic standard statements. In general these statements will themselves be broken into sub-statements, etc. The CASE specification defines a data model for this hierarchical structure with the hierarchy determined using a linked list approach.

3.2. Logical Data Model

The data model for the CASE specification consists of a set of core classes which are used to define the data properties. A logical representation of the logical data model for the data structures in the CASE service is shown in Figure 3.3.

3.3. Package Structure

A Competency Framework Package (CFPackage) is the structure that is used to contain a CFDocument and all of the associated components to create a complete and standalone structure i.e. a system using the CFPackage has no need for other contextual data. A schematic representation of the structure of a CASE package is shown in Figure 3.4.

3.4. Interoperability Model

The CASE service defines how data about learning standards and competencies is exchanged. It does not address how the data is stored and/or processed in the end-systems that exchange the information. A schematic representation of the service provided by the CASE specification is shown in Figure 3.5.

4. Service Architecture and Specification Model

4.1. An Abstract Representation

It is important to remember that this document contains a description of the underlying information model in terms of the abstract Application Programming Interface (API). The manner in which this abstract representation is visualized is not intended to dictate the implementation form of the Service. The breakdown of the service into its interface classes is a convenient way to document the set of behaviors. The objective for producing these interfaces is to identify and define the messages that are exchanged between the end-systems to realize the system behaviors required of the service.

The internal organization of an implementation of the full abstract API is beyond the scope of this specification. The only constraint is that the external behavior of the abstract API complies with this specification. This means that a .NET, J2EE, etc. physical implementation of this abstract API does not have to represent the functionality using the same breakdown of operations/methods. This physical implementation is not subject to the conformance specification.

It is important to note that the UML representation of the interfaces is used to help develop and document the Information Model and various Bindings. It is not a requirement for a system to implement this interface as defined i.e. to use the same parameters, etc. Conformance against this specification will be confirmed by inspecting the appropriate binding of the information model and ensuring that the relevant information is present and that different sequences of activity result in the predicted and mandated behavior. It is essential that the behaviors described by each of the operations are fully supported and that the behaviors described by different sequences are also maintained.

4.2. Service Architecture and Specification Model

The basic architectural model for the CASE Service specification is shown in Figure 4.1. In this architecture the scope of the IMS CASE Service specification is shown as the dotted line. The scope of the interoperability is the data and behavioral models of the objects being exchanged.

4.3. Service Objects

The set of service collection objects that are exchanged between end-systems are:

4.4. A Synchronous Service

The CASE Service is a synchronous service i.e. the consumer is blocked until the response from the provider is received. This means that a consumer can only have one outstanding request with a service provider. The corresponding sequence of actions is shown in Figure 4.2.

5. The Behavior Model

5.1 Service Definition

Table 5.1 The set of interfaces.
Interface	Description
AssociationsManager	The set of service operations that manage access to the Competency Framework Associations. Associations are to establish relationships between definitions from different sources. This interface manages the associations between CFDocuments and between CFItems.
DefinitionsManager	The set of service operations that manage access to the Competency Framework Definitions. This interface manages the definitions of the: Competency Framework Concepts, Competency Framework Subjects, Competency Framework Licenses, Competency Framework Item Types and Competency Framework Association Groupings.
DocumentsManager	The set of service operations that manage access to the Competency Framework Documents. Documents are the root entry point for the definition of an academic standard/competency. This interface manages the document descriptions only i.e. it does not support the management of Items, Associations, etc.
ItemsManager	The set of service operations that manage access to the Competency Framework Items. Items are the containers for the definitions in an academic standard/competency. This interface manages the Item descriptions only i.e. it does not support the management of Associations, etc.
PackagesManager	The set of service operations that manage access to the Competency Framework Packages as a whole. A Competency Framework Package is a package that contains all of the arefacts that are used for the definition of a Competency Framework Document.
RubricsManager	The set of service operations that manage access to the Competency Framework Rubrics. Rubrics associate the set of rubric criteria being defined for a specific academic standard/competency (defined as either a CFItem or a CFDocument).

8.1.2. Proprietary Data Elements

8.2. Profiling the Service

Valid Profiles must be restrictive i.e. optional features can be removed or constraints increased but new features must not be added. A Profile of this service is made by annotating the UML supplied with the documentation for the specification.

It is strongly recommended that a profile of this specification is undertaken either by, or with the close support, of IMS Global. However, no matter who is responsible for creating the profile artefacts (documents, OpenAPI files, XSDs, etc.), it is strongly recommended that the IMS specification tools are used. This will ensure that the artefacts are consistent with the base specifications and that useful support documentation is automatically produced e.g. creation of a document that summarises the differences between the base specification and the profile. Organizations wishing to produce a profile of this specification should contact Lisa Mattson (IMS Global Chief Operations Officer) at: lmattson@imsglobal.org.

A-API	Abstract API
API	Application Programming Interface
CASE	Competencies and Academic Standards Exchange
CBE	Competency Based education
Competency Framework	A set of statements created by and articulating skills and/or specific knowledge.
Competency Framework Association	A relationship between two Competency Framework Documents or two Competency Framework Items (the associations are defined using a set of predefined vocabulary).
Competency Framework Association Grouping	This is a set of associations that have been grouped together because they have some important relationship(s). One usage would be in identifying the set of cross-walk associations to other documents.
Competency Framework Document	A document that acts as a container for a collection of learning standard items, typically arranged in a hierarchical structure or classification scheme, reflecting expectations of learner competencies within a single subject area covering one or more levels.
Competency Framework Item	Content that either describes a specific competency (learning objective) or describes a grouping of competencies within the taxonomy of a Competency Framework Document. Educational standards are the learning goals for what students should know and be able to do at each grade level. Education standards, like Common Core are not a curriculum. Local communities and educators choose their own curriculum, which is a detailed plan for day-to-day teaching. In other words, the Common Core is what students need to know and be able to do, and curriculum is how students will learn it. The Common Core State Standards are educational standards for English language arts (ELA)/literacy and mathematics in grades K-12.
Competency Framework Package	A set of Competency Framework Document, Competency Framework Items and Competency Framework Associations released by a standard setting entity
Competency Framework Rubric	An entity that includes information about an instrument used to communicate expectations of quality around a task, product, or performance and/or used to delineate consistent criteria for grading. A CFRubric is defined by a set of CFRubricCriterion.
Competency Framework Rubric Criterion	An entity that defines a specific performance criterion. A CFRubricCriterion is defined by a set of CFRubricCriterionLevels.
Competency Framework Rubric Criterion Level	An entity that defines a specific performance criterion level for a rubric. Each level must have a distinct performance value.
