Final Deliverable, Supervisor Evaluation, and Externship Debrief

Lesson Overview

You have reached the final milestone of your externship placement. This lesson guides you through three interconnected tasks: presenting a polished final worksite artifact, sitting for a formal employer evaluation, and participating in a program debrief that sets you up for Exam Prep (Course 14). Completing all three tasks—and meeting the minimum score thresholds—is what earns you credit for the externship course.

Finalizing and Presenting Your Capstone Artifact

Your final presentation is a professional deliverable, not a classroom exercise. Treat it as you would a real business presentation. Structure it around a clear story: open with the business question your project addressed, describe the data sources and methods you used, share key findings supported by at least two visualizations, acknowledge limitations honestly, and close with specific recommendations.

Target a 10-to-15-minute delivery followed by five minutes of Q&A. Practicing out loud at least twice beforehand is strongly advised. Arrive early, confirm that projector or screen-share connections work, and have a backup copy of your slides or report on a USB drive or cloud link. If your site supervisor invites a small team audience, that is an opportunity, not a threat—it mirrors real workplace presentations and signals that your work has organizational value.

Strong visualizations follow basic data-integrity rules: axis labels are present and honest, scales are not truncated to exaggerate differences, color choices are accessible to people with common forms of color blindness, and every chart has a title that states the finding, not just the topic. These habits are tested in the CompTIA Data+, Google Data Analytics, and Microsoft PL-300 exams, so practicing them now reinforces certification readiness.

The Employer Evaluation Form

After your presentation your supervisor completes the program's Employer Evaluation Form, a five-domain rubric covering: technical skill, data-quality standards, professionalism, communication, and workplace safety behaviors. Scores run from 1 to 5 on each domain. You must earn a 3 or higher on every domain to pass the externship without remediation.

Schedule a closing feedback meeting with your supervisor to review the completed form together. During that meeting, listen actively, ask clarifying questions, and avoid becoming defensive. Your goal is to leave with three specific, actionable takeaways recorded in your externship journal. Write them in concrete terms: not "improve communication" but "practice explaining statistical uncertainty to non-technical stakeholders before presenting findings."

If any domain scores below 3, you are not blocked from completing the debrief, but you must submit a written remediation plan approved by the program coordinator before Course 14 begins. Be honest with yourself: a low score now, addressed deliberately, is far less costly than discovering the same gap during a certification exam or a job interview.

Workplace Safety in a Data Environment

Data science workplaces may not involve heavy machinery, but they carry real safety and compliance obligations. During your placement you should have followed all site policies for data handling, including rules about personally identifiable information (PII), secure disposal of printed data, and locking workstations when stepping away. On your evaluation form, the workplace safety domain reflects these behaviors—not just physical safety. Document in your journal any site-specific policies you encountered so you can reference them during the debrief and in future employment.

The Program Debrief Session

The debrief is a structured group session facilitated by your program coordinator, held in person or virtually. You will deliver a five-minute summary covering: what you did at the site, what your final artifact accomplished, the three most important skills you practiced, and two competency gaps you will prioritize in Exam Prep.

The two gaps you name should map to specific credential domains—for example, a weakness in SQL window functions maps to the IBM Data Science Professional certificate, and a gap in DAX measures maps to the Microsoft PL-300. Use the credential domain gap-analysis worksheet provided with this lesson to make that mapping explicit. This worksheet becomes the first input for your Course 14 study plan.

At the close of the debrief you submit your complete externship portfolio to the program coordinator. That portfolio must contain: your externship journal (all entries), your final worksite artifact and any mid-point deliverables, and the signed Employer Evaluation Form.

Assembling the Portfolio

Organize your portfolio so a reader can navigate it without your help. A brief table of contents, consistent file naming, and a one-page summary of the placement (employer, dates, project description, key outcomes) make a professional impression and are good habits for the job search ahead. Employers in data science frequently ask candidates to share work samples, and a well-organized portfolio can substitute for work samples you cannot share due to confidentiality agreements.

Preparing for Course 14

This externship was the applied bridge between your classroom training and your certification exams. The debrief and gap-analysis worksheet are designed to make the transition deliberate rather than accidental. When you begin Exam Prep, you will have a concrete list of domains to strengthen, real project experience to draw on for scenario-based questions, and a supervisor evaluation that tells you honestly where you stand. That combination is a significant advantage.
