schema, which is a defined
structure based on standard tag-based formatting instructions. XML applications work with a schema to
allow institutions to transfer data in a format (extract file) that will be understood between varying
applications.
An XML schema is comprised of elements, also known as data elements. Elements can be blank,
required, or optional as specified by the schema. Elements also can be repeated if declared in the
schema. An example of this type of data element is a course grade. Other elements can be limited to a
single instance by the schema. An example of this type of data element is the student name.
Data elements that are shown as coded, refer to enumerated values for data types within the schema,
which is similar to using a code table. These are included in or defined as part of an XML Simple Type. To
reuse common data elements (such as Address, City, StateProvince and PostalCode), simple types are
grouped within a Complex Type. A data element is further defined by the related complex type within the
schema.
This section describes each of the TREx data elements. A legend of the information found on each data
element definition follows:

Indication whether the field is required or optional Yes - the element is required; if the requirement is only for specific grade
levels, this is noted; NA may be entered if data are not available/applicable No - the element is optional and may be left blank unless specified

the accuracy and completeness of the student record or transcript, it is the
responsibility of the campus to include these data. Examples include
indicators for ESL, Bilingual, GT, CTE, At Risk, Title I Part A, Special
Education, IEP, Personal Graduation Plan, Migrant, and Homeless.
