CK-12 is a free digital learning platform centered on FlexBooks and standards-aligned resources. It is designed primarily for primarily middle- and high-school learners, with content extending into elementary and college-preparatory subjects, with students, teachers, curriculum writers, and families using it to support open textbooks, simulations, practice, adaptive learning, and customizable stem resources.

Teachers can adopt, remix, and assign digital texts, interactives, questions, simulations, and practice while students use them for instruction, reference, or review. The product should be evaluated for the specific learners, instructional setting, and intensity of support a district intends—not simply as another source of digital activities.

Class Composer is an elementary class-placement tool that helps school teams create balanced classroom rosters for the next school year. Educators enter or import student characteristics, relationships, services, academic information, and placement considerations, then compare proposed class groupings.

The product supports the internal placement of already enrolled students; it does not collect family registration forms or establish SIS enrollment. It belongs under Student Scheduling / Class Placement and should be moved after the district relationships are retained.

ClassLink is a K–12 access, rostering, identity-management, and application-analytics platform. LaunchPad gives students and staff a role-based single sign-on portal; Roster Server distributes SIS roster data to learning applications; OneSync automates account and group changes; and Analytics provides application-use reporting. Analytics+ is an additional offering with deeper analysis.

The products are designed to work as a shared connection layer across a district's technology environment. ClassLink can import SIS and directory data, transform it to the OneRoster standard, send only approved fields to vendors, support SAML, OAuth, and LTI access, and connect cloud storage and other school resources. This lets districts add or change applications without rebuilding a separate login and roster process each time.

LaunchPad is the user-facing application portal. District administrators use the ClassLink Management Console to administer their ClassLink environment. These are related parts of ClassLink, rather than evidence that a district has adopted an unrelated standalone system.

Rostering software that connects student information system data to educational applications through OneRoster. ClassLink Roster Server manages scheduled data sharing, preprocessing, and vendor connections so schools can maintain consistent accounts and class rosters across learning tools.

Not to be confused with: ClassLink LaunchPad provides single sign-on; Roster Server provides roster data exchange.

classroom.cloud is a three-part K–12 platform for classroom management, student safeguarding, and basic IT device management. Teachers use it to view student screens, share content, control applications and web access, communicate, and keep students focused; safeguarding teams monitor concerning activity and student-submitted concerns; technology staff manage supported classroom devices and settings.

Because those functions serve teaching, student safety, and IT operations as distinct district responsibilities, classroom.cloud meets the original Integrated Systems concept more directly than most listings in this category. It should also be cross-listed with Classroom Management, Student Safety/Monitoring, and Device Management.

CodeCombat is a game-based programming curriculum and practice environment. It is designed primarily for upper-elementary through high-school learners beginning or extending computer programming, with computer-science teachers, students, after-school programs, and curriculum leaders using it to support coding syntax, computational thinking, problem solving, and computer-science concepts.

Students write real code to solve progressively structured game challenges while educators assign courses and monitor concept mastery. The product should be evaluated for the specific learners, instructional setting, and intensity of support a district intends—not simply as another source of digital activities.

CodeHS Pro is the paid school edition of CodeHS’s secondary computer-science curriculum and platform. It is intended primarily for middle- and high-school learners in computer science, cybersecurity, web, and technology courses, with students, computer-science teachers, CTE staff, counselors, and curriculum leaders using it to support programming, computational thinking, cybersecurity, web development, and course assessment.

Teachers deliver sequenced courses, coding exercises, projects, quizzes, sandboxes, and feedback while monitoring progress and code submissions. Districts should evaluate how the product fits adopted curriculum, student needs, instructional time, and the work educators must do around it.

ContentKeeper provides web filtering for K–12 networks and managed devices. Its hybrid design combines on-network filtering with cloud protection for supported off-campus devices, giving IT staff a common framework for access policies and reporting.

ContentKeeper Technologies is part of Ativion, the group that also includes Impero’s education offerings. Current product information describes supported-device coverage, encrypted-traffic visibility, granular video controls and safeguarding alerts; availability depends on configuration and licensing.

Not to be confused with StudentKeeper, Ativion’s related classroom-management and safeguarding offering. A ContentKeeper filtering connection does not establish that a district has licensed StudentKeeper or every available module.

D’Nealian Handwriting is Savvas’s handwriting curriculum using the D’Nealian manuscript-to-cursive approach. It is intended primarily for elementary learners developing manuscript and cursive handwriting, with students, elementary teachers, occupational-therapy partners, and families using it to support letter formation, manuscript, cursive, fine-motor practice, and written fluency.

Students practice letter strokes, spacing, words, sentences, and connected writing through print and digital resources. Districts should evaluate how the product fits adopted curriculum, student needs, instructional time, and the work educators must do around it.

Deledao is a K–12 web-filtering, classroom-management, and student-wellness platform built around real-time analysis of page text, images, video, and activity. ActiveScan filters inappropriate or distracting content, ActiveInstruct gives teachers classroom controls, and ActivePulse identifies concerning language or behavior for authorized support teams.

Unlike filters that rely primarily on preclassified domains, Deledao evaluates page-level context and media as students use it. Districts can combine automated filtering with teacher unblock workflows, parent visibility, reporting, and human review of high-risk wellness alerts; they should document which modules and monitoring practices are enabled.

Divot Assets provides K–12 fixed-asset inventory software together with optional physical inventory and audit services. Districts use it to maintain records for technology, furniture, equipment, buildings, and other capital or controlled property across schools and departments.

The platform records acquisition, funding source, location, custody, condition, value, transfers, and disposition and supports barcode-based fieldwork and required reports. Divot can also conduct district-wide inventories, establish a baseline register, and help reconcile physical findings with existing records.
