Who gets the test?

This is a hypothetical clinic, not a report about real patients. The clinic has 50 test kits and 400 people asking for a test. These counts show a shortage. They do not tell us who is infected, how accurate the test is or what outcomes any rule would produce.

Your main task is one individual argument explaining a rule for distributing the tests. You will also attach a separate, short official-source/progress record. The model, guided notes and partner discussion support these two tasks; they are not extra submissions.

Allocation means distributing a limited resource. A criterion is a rule used to judge a choice. A tradeoff is a benefit gained alongside a cost or an opportunity given up.

Evidence describes information that is supplied or known. Here, the test and demand counts are supplied scenario facts. A value judgment states what you think should matter most. Saying that greatest need should come first is a priority choice, not a measured test result.

CER means claim, evidence and reasoning. The claim states your rule. Evidence supports your argument. Reasoning explains the connection between your evidence and the value guiding your rule. A rebuttal answers an opposing argument by addressing its strongest point.

This is a text reference, not patient data. Each framework uses a different priority criterion.

Most need

Criterion: Give priority to those with the greatest need under a stated criterion.

Tradeoff: This takes need seriously, but need alone may not capture every other value.

Most benefit

Criterion: Give priority where the resource is expected to help most, using a stated measure of benefit.

Tradeoff: The expected benefit needs supporting information and leaves uncertainty.

First-come

Criterion: Give priority by arrival order.

Tradeoff: The order is clear, but people may have different opportunities to arrive.

Text equivalent: most need uses a stated need criterion; most benefit uses a stated expected-benefit criterion; first-come uses arrival order. For any choice, state its criterion and a possible tradeoff. The 50-kit/400-person counts do not rank the people or establish a uniquely fair answer.

1. Claim: state the allocation rule you would defend and the criterion behind it. You are defending a rule, not diagnosing or ranking named patients.
2. Evidence: write at least one sentence using the supplied scenario facts. Use the information provided, without inventing infection rates, contacts, predicted outcomes or test performance.
3. Reasoning: explain how those facts and your stated value support the rule. Identify who may benefit and who may wait, without claiming those outcomes have been measured.
4. Limitation: state one uncertainty or limit. The scenario does not supply the individual information needed to decide who would qualify under every rule.
5. Rebuttal: give the strongest point of a different framework and answer it. A useful rebuttal acknowledges a real tradeoff instead of dismissing the alternative.

These are five parts of one CER, not five uploads. You do not need two empirical findings or a separate evidence-ID list. Partner exchange and reading other rules, when available, help you revise the same argument. No separately posted replies are required. If no partner is available, use one of the supplied alternative frameworks for the rebuttal.

This hypothetical scenario supports comparing allocation rules and tradeoffs. It cannot establish patient outcomes or a uniquely fair clinical answer. A value judgment is not a measured result.

The separate kidney-allocation model shows how to organize an argument about another hypothetical shortage. Its people and numbers are not information about this clinic. Do not copy a kidney outcome or clinical ranking into your test-allocation argument.

Use one short Google Doc with three brief entries:

1. Official source: Activity 1.1.5, ELISA. Include the supplied official-source link. Your existing myPLTW account is the course hub.
2. Actual progress: say what you actually opened or completed, or describe the access obstacle. An access problem is something to record, not a reason to invent completed work.
3. Next step: name your next assigned step, or the step for which you need teacher direction. Do not invent a future assignment.

Attach that Doc to assignment 8520302557. Do not put another CER or copied official-handout answers in this checkpoint. It records progress; it does not certify that you completed Activity 1.1.5.

Activity 1.1.5 connects antigen binding, dilution, controls and test results to an investigation. Today's local allocation discussion considers the ethical context of testing. It does not run an assay, complete the official activity or authorize a wet lab. No patient result, vendor procedure or dilution worksheet is required to finish this argument.

The Belmont Report is optional background about ethical principles in research. It does not supply patient outcomes or a uniquely correct allocation rule for this clinic. The reading and model here contain the information needed for your local argument.

• CER, assignment 8520302515: one PDF by September 16 at 11:59 p.m. If your teacher collected your paper CER, the existing collected-paper exception applies. This item is 15 points in Assessments.
• Source/progress record, assignment 8520302557: attach one short Google Doc with the three entries above by September 16 at 11:59 p.m. This item is 6 points in PLTW Work. The paper exception applies to the CER only.

Guided notes, reflection and the worked model are optional support, not additional submissions.
