Enabling an organization to control user assignments and assessment results while enabling a proprietary provider to maintain control over both network distribution of proprietary content comprising the assignments and use of proprietary assessment functions that evaluate the user's performance of the assignments. A student uses a browser to submit a request to a learning management system (LMS) that includes a URL to a network node hosting the proprietary learning content and assessment functions. The LMS sends a hidden form to the browser, causing the browser to automatically redirect to the network node. The proprietary provider then controls distribution of the proprietary learning content to the browser and controls the student's interaction with the proprietary learning content to accomplish the assignment. When the student submits responses to the assignment, the proprietary provider performs proprietary assessment functions and redirects only results data to the LMS through the browser.
