Course 09 Grade 4 — Community Systems and Service
Version: 1.0 public self-study edition — October 12, 2026 Status: Free public, supervised, noncredit curriculum; not approved for enrollment, school credit, diploma, credential, licensure, placement, or funding claims.
Promise and boundary
I can understand how people and systems depend on each other, map a process, and improve one part responsibly. Learners use fictional, public, or minimum-necessary information in supervised simulations. The course does not authorize interviews with real people, live accounts, public contact, protected records, regulated work, purchases, or decisions about a person.
Humanization is the parent doctrine. Systems and tools must preserve dignity, agency, truth, safety, privacy/security, accessibility, authorship, and human accountability. AI may assist a bounded task only when disclosed and checked; it is not the author, conscience, or decision-maker.
Portfolio and rhythm
The learner produces a community-role map, stakeholder/needs brief, permission-based observation plan, process map, data/diagram record, improved prototype, before/after evidence, handoff/repair log, inclusion/safety map, public-resource/value brief, systems explanation, and service-system capstone. Each unit follows Learn → Practice → Prove → Use → Advance.
Twelve-unit sequence
Unit 1 — Interests and Community Roles
Learn: interest, strength, role, responsibility, support, and human worth differ. Practice: sort fictional community roles without ranking people. Prove: make a role-and-interest map using chosen, non-sensitive details. Use: explain one possible contribution without making an identity promise. Advance: select one safe skill to practice.
Unit 2 — Users, Stakeholders, and Needs
Learn: user, stakeholder, need, request, impact, and assumption differ. Practice: map fictional stakeholders and affected groups. Prove: create a needs brief with unknowns and accessibility questions. Use: ask a clarifying question in a simulation. Advance: identify a source or observation route.
Unit 3 — Interview and Observation with Permission
Learn: permission, notice, voluntary choice, observation, question, and privacy. Practice: repair a fictional plan that asks for too much information. Prove: submit a no-contact or approved-context observation plan with stop rules. Use: practice listening without guessing or recording protected details. Advance: name the human owner who must approve context.
Unit 4 — Map a Process and Find Bottlenecks
Learn: step, handoff, owner, queue, bottleneck, failure, and success criterion. Practice: map a fictional classroom or service process. Prove: create a process map with one bottleneck and one unknown. Use: explain how a delay affects different people. Advance: choose one low-risk improvement to test.
Unit 5 — Data Tables, Diagrams, and Simple Automation
Learn: data field, label, pattern, diagram, rule, automation, and review. Practice: build a small fictional table and diagram with no personal data. Prove: document a human-reviewed rule or automation idea. Use: identify where a person must check the result. Advance: record a no-tool or offline alternative.
Unit 6 — Build an Improved Process or Prototype
Learn: prototype, requirement, constraint, user support, and intended use. Practice: sketch a small improvement and predict two failure cases. Prove: build version one with scope, sources, support, and authorship disclosure. Use: demonstrate it in a fictional or approved safe setting. Advance: select a revision based on evidence.
Unit 7 — Compare Before/After Evidence
Learn: baseline, comparison, measure, observation, limitation, and inference. Practice: compare fictional before/after records without claiming causation. Prove: make a dated evidence table with assumptions and noncoverage. Use: explain what changed and what remains unknown. Advance: write one correction or next test.
Unit 8 — Handoffs, Responsibility, and Repair
Learn: owner, handoff, escalation, repair, feedback, and continuity. Practice: role-play a missed handoff and respectful repair. Prove: create a handoff/repair record naming next owner and date. Use: communicate a correction without blame or concealment. Advance: identify the next safe checkpoint.
Unit 9 — Bias, Inclusion, Access, and Safety
Learn: bias, barrier, inclusion, accessibility, safety, consent, and stop authority. Practice: classify scenarios as proceed, ask, pause, escalate, or stop. Prove: complete an inclusion/safety map with an alternate route. Use: explain one design choice that reduces burden or exclusion. Advance: write a hold statement for an unresolved risk.
Unit 10 — Public Resources and Fair Exchange
Learn: public resource, cost, value, contribution, tradeoff, and fair exchange. Practice: compare fictional resource choices without private financial data. Prove: make a dated resource/value brief with assumptions and limits. Use: rewrite a promise into evidence-supported language. Advance: identify the authorized source for an unresolved rule.
Unit 11 — Explain the System and Limits
Learn: system boundary, evidence, audience, explanation, uncertainty, and transfer. Practice: explain a process to a fictional newcomer using a diagram. Prove: present the system, improvement, evidence, and limitation independently. Use: apply the method to a new low-risk process. Advance: record one evidence gap and practice task.
Unit 12 — Service-System Improvement Capstone
Learn: service, continuity, consent, access, correction, and next step. Practice: audit the complete packet for source, safety, access, and ownership. Prove: deliver a fictional/public or approved low-risk process improvement with map, evidence, handoff, inclusion route, and limits. Use: defend one choice to proceed, revise, or stop. Advance: create a 30-day practice plan with owner, support, risk, and alternate route.
Completion rule
Completion requires twelve evidence items or approved accessible equivalents, facilitator review, correction, disclosed assistance, independent explanation or transfer, and all noncompensable gates. Safe wording: “The learner completed the noncredit DTU course and demonstrated the listed tasks at the documented support level.”

Assessment and accessibility
Use the task-level 0–4 scale: not yet shown; direct help; limited help; independently here; transfers and helps. Never score intelligence, dignity, character, accent, disability, family, immigration, trauma, or future potential. Offer oral, written, visual, demonstrated, translated, captioned, large-print, keyboard, extra-time, offline, and assistive-technology routes when they preserve the target. Require correction and retest.
Pause and escalate for unsafe work, missing authority/consent, protected data, inaccessible evidence without an alternative, discrimination/harassment, false claims, undisclosed material assistance, real-person profiling/decision, public contact, account creation, purchase pressure, live regulated activity, or unsafe tool failure.
Closeout
Confirm twelve evidence items or accessible equivalents, source/date/limits, correction, assistance disclosure, independent explanation, noncompensable gates, next owner/date/source, alternate route, and human escalation. Safe wording: “The learner completed the noncredit DTU course and demonstrated the listed tasks at the documented support level.”

Course 09 Grade 4 — Service-System Improvement Capstone Rubric
Brief
In a supervised fictional, public-data, or low-risk simulation, the learner maps a process, identifies a human need, designs a bounded improvement, tests it, documents before/after evidence and limits, protects privacy, provides an accessible route, and completes a handoff. No protected records, live accounts, real-person profiling, public contact, purchases, financial advice, regulated work, or unsupported outcomes.
Evidence packet
- role/interest map; 2. stakeholder/needs brief; 3. permission/observation plan; 4. process map; 5. data/diagram record; 6. prototype v1; 7. before/after evidence; 8. handoff/repair log; 9. inclusion/safety map; 10. resource/value brief; 11. system explanation; 12. capstone and 30-day plan.
