Our Taxonomy is the EdGate “Concept Index”

At the core of EdGate’s business is the EdGate taxonomy. EdGate has been engaged in an ongoing process of creating our educational taxonomies for well over a decade. The basis for our taxonomy is rooted in the educational standards from both the United States and International standards and the refinement of our taxonomies over time has given us the ability to fully understand what is being taught in classrooms across the world.

The EdGate taxonomy, referred to as the Concept Index, is a list of standards-based educational concepts broken down by subject area. The EdGate Taxonomy reflects concepts that are taught as part of the educational standards in each subject area. It is the source by which any piece of content can be directly aligned to all applicable standards in one step. 

For example, when a content unit (such as a video or lesson) has been tagged with a concept, using EdGate’s patented technology, the concept dynamically “marries” the content to the applicable standards.  It is through the concepts that the content correlates to the standards. 

In fact, it is our robust taxonomy of concepts that allows EdGate to provide the most accurate standards crosswalks/mapping services in the education industry. For instance, we can take existing alignments to the U.S. Common Core standards and crosswalk/map those alignments to the Texas TEKS standards, etc.

License the EdGate Taxonomy

EdGate packages and licenses the Concept Index by subject with all associated standards. The index for the four core subjects (Language Arts, Math, Science, and Social Studies) includes 1,500 of the top concepts per subject which attains approximately 90% standards coverage. Other subjects are also available. 

Taxonomy Creation Services

Additionally, EdGate can create a taxonomy for any subject area, at any educational level, and align the taxonomy to content or educational outcomes. Publishers who need to organize content, create a hierarchy, correlate by concept or have a specific need for a taxonomy call upon EdGate to create taxonomies based on specific requirements. For example, for our higher education and professional publishing clients, we’ve created taxonomies for Microsoft Office applications and computer concepts. We’ve then aligned the taxonomies to Microsoft Office Specialist (MOS) certification outcomes and to IC3 certification outcomes.

Learning Progressions/Content Sequencing

A learning progression is a sequencing of teaching and learning expectations across multiple developmental stages, ages, or grade levels. Learning progressions are often categorized by subject area and used in reference to educational standards. Learning progressions are a way to think about the order of how students achieve mastery of a skill set. Assessments that are developed using a learning-progressions model can more precisely identify areas in which students may be underperforming. This process helps teachers better understand what students need so that they can apply an appropriate intervention. Per the EdGlossary definition, a Learning Progression is as follows: There are two main characteristics of learning progressions: (1) the standards described at each level are intended to address the specific learning needs and abilities of students at a particular stage of their intellectual, emotional, social, and physical development, and (2) the standards reflect clearly articulated sequences-i.e., the learning expectations for each grade level build upon previous expectations while preparing students for more challenging concepts and more sophisticated coursework at the next level.

Through the use of our proprietary technology, EdGate can provide a learning progression of standards in a specific state; data on how standards-aligned content progresses vertically; and gaps in a content within the learning progression.
