Detailed Grading Criteria
Mathematical Validity & Procedural Fluency
40%“The Engine”CriticalEvaluates the correctness and precision of the mathematical work. Measures the student's execution of algorithms, application of formulas, and accuracy of calculations, independent of how they are explained or formatted.
Key Indicators
- •Selects and applies appropriate mathematical models, formulas, or theorems.
- •Executes algorithmic procedures without computational errors.
- •Calculates final results with accuracy appropriate to the problem context.
- •Maintains consistent notation, units, and significant figures throughout derivations.
- •Verifies results against constraints or estimation to ensure mathematical viability.
Grading Guidance
To move from Level 1 to Level 2, the student must demonstrate a basic recognition of the correct mathematical tools required for the task. While Level 1 work is characterized by fundamental misconceptions or irrelevant calculations, Level 2 work identifies the correct general approach or formula, even if the execution is riddled with arithmetic errors or misapplications of variables. The transition to Level 3 marks the shift from conceptual recognition to procedural competence. At Level 3, the student successfully carries out standard algorithms and reaches a solution that is largely correct; errors are minor (e.g., a sign error or simple arithmetic slip) and do not derail the validity of the chosen method. Advancing to Level 4 requires the elimination of computational slips and the consistent application of notation and units. While Level 3 accepts a result that is methodologically sound but imprecise, Level 4 demands precision, correct handling of edge cases, and accurate multi-step procedures without loss of fidelity. Finally, Level 5 work is distinguished by sophistication and self-validation. The student not only calculates correctly but chooses the most robust method available and explicitly verifies results against constraints or through estimation, demonstrating a command of the mathematics that goes beyond rote application to rigorous proof of validity.

Conceptual Reasoning & Interpretation
30%“The Insight”Evaluates the transition from calculation to conclusion. Measures how effectively the student justifies their methodological choices, interprets numerical results within the context of the problem, and identifies limitations or implications of their findings.
Key Indicators
- •Justifies selection of mathematical models or algorithms based on problem constraints
- •Translates numerical outcomes into context-specific conclusions
- •Validates results against initial assumptions or real-world logic
- •Analyzes limitations or potential sources of error in the chosen method
- •Synthesizes multiple mathematical findings to support a cohesive argument
Grading Guidance
Moving from Level 1 to Level 2 requires the student to shift from providing raw calculations to attempting basic verbal explanations; the work must show an awareness that the numbers represent real-world quantities, even if the interpretation is generic or slightly disconnected. To cross the threshold into Level 3 (Competence), the student must accurately link specific numerical results to the problem's context without prompting. The explanation shifts from merely describing the procedural steps taken ("I multiplied x by y") to justifying the methodological choice ("I used this formula to determine the rate of change"). Progressing from Level 3 to Level 4 involves a leap from correctness to critical analysis. While a Level 3 report states the correct answer, a Level 4 report validates it, explicitly checking for reasonableness and explaining the significance of the findings within the project's scope. Finally, achieving Level 5 (Excellence) distinguishes itself through nuance and rigorous self-reflection. The student not only provides a robust conclusion but also critiques their own methodology, identifying specific limitations, constraints, or potential sources of error that affect the reliability or applicability of the final result.
Proficiency Levels
Distinguished

- •Justifies method by explicitly connecting mathematical assumptions to physical reality
- •Analyzes the impact of limitations (e.g., states whether the result is an over/underestimate)
- •Synthesizes results to propose a logical next step, prediction, or solution
↑ Unlike Level 4, the work analyzes the impact or significance of limitations rather than simply identifying them.
Accomplished
Provides thorough justification for methodological choices and clearly interprets results within the specific constraints of the problem context. The reasoning is logical, cohesive, and clearly communicated.
Is the reasoning logically structured with specific justification for methods and clear interpretation of results?
- •Justification cites specific problem features rather than generic rules
- •Interpretation explicitly references project constraints (e.g., budget, dimensions, safety)
- •Identifies specific, non-generic limitations inherent to the chosen method
↑ Unlike Level 3, the justification and interpretation address the specific nuances of the problem scenario rather than applying a standard template.
Proficient

- •Justification is circular (e.g., 'I used the formula because it is the formula')
- •Interpretation is generic (e.g., 'The number looks correct') rather than context-specific
- •Mentions that errors might exist without identifying a specific source
↑ Unlike Level 1, there is a distinct attempt to explain the reasoning behind the numbers, even if that reasoning is flawed or thin.
Novice
Presents calculations in isolation with little to no reasoning, or draws conclusions that are unsupported by or contradictory to the mathematical evidence.
Is the work missing fundamental connections between the calculation and the conclusion?
- •Presents raw calculation results without sentence-based interpretation
- •Conclusion contradicts the calculated data
- •Omits justification for the method selected
Structural Organization & Logic
15%“The Blueprint”Evaluates the logical architecture of the report. Measures the sequencing of information—from problem statement to methodology to analysis—ensuring the reader is guided through the mathematical argument without gaps in logic.
Key Indicators
- •Sequences report sections to build a coherent narrative from hypothesis to conclusion.
- •Connects the problem statement directly to the selected mathematical models.
- •Justifies specific logical transitions between mathematical steps to prevent gaps.
- •Integrates visual aids (graphs, tables) at relevant points to advance the argument.
- •Synthesizes analysis results to provide a distinct answer to the research question.
Grading Guidance
Moving from Level 1 to Level 2 requires organizing raw mathematical notes into a recognizable report structure; the student must group related calculations and text under appropriate headings rather than presenting a scattered stream of consciousness. To progress from Level 2 to Level 3, the student must ensure logical consistency between these sections; the methodology selected must clearly address the problem defined in the introduction, and the conclusion must accurately reflect the data derived, eliminating major contradictions or non-sequiturs. The jump from Level 3 to Level 4 involves the explicit justification of mathematical choices; the student moves beyond simply listing operations to explaining the reasoning behind specific logical transitions, ensuring the reader follows the argument's complexity without needing to guess. Finally, reaching Level 5 requires a seamless synthesis where the mathematical argument is elegant and tightly woven; the report anticipates potential reader confusion, integrates visual evidence perfectly into the logical flow, and presents a compelling, gap-free narrative from the initial prompt to the final solution.
Proficiency Levels
Distinguished
The report demonstrates a sophisticated, cohesive narrative where the mathematical argument flows seamlessly from the problem statement to the solution.
Does the report weave a cohesive narrative where the mathematical logic is seamlessly integrated, self-explanatory, and effectively guides the reader?
- •Uses explicit 'signposting' sentences to guide the reader (e.g., 'To verify this, we next applied...')
- •Integrates mathematical steps and textual explanation so neither stands in isolation
- •Anticipates potential reader confusion by clarifying complex logical transitions
- •Structure reinforces the argument (e.g., placing a critical diagram exactly where the text references it)
↑ Unlike Level 4, the structure is used strategically to enhance the clarity and persuasion of the argument, rather than just organizing information efficiently.
Accomplished
The work is thoroughly developed with a clear, linear progression that links the problem, methodology, and conclusion with strong transitions.
Is the report logically sequenced with clear transitions that directly link the problem statement to the final conclusion?
- •Contains distinct Introduction, Method, Analysis, and Conclusion sections that flow logically
- •Transitions between paragraphs clearly link the previous idea to the next
- •Mathematical steps are shown in full sequence without 'magic' jumps
- •The conclusion explicitly references the initial problem statement
↑ Unlike Level 3, the report uses transition statements to connect sections, creating a unified document rather than a series of isolated parts.
Proficient
The work follows a standard report structure (e.g., Introduction, Body, Conclusion) with functional sequencing that allows the reader to follow the procedure.
Are all required sections present and ordered in a way that allows the reader to follow the basic mathematical procedure?
- •Organizes content into standard headers (Introduction, Method, Results)
- •Presents the problem statement before the solution
- •Mathematical steps are sequential (Step A leads to Step B)
- •Includes all necessary components of the assignment, though transitions may be abrupt
↑ Unlike Level 2, the logical flow is continuous without significant gaps that prevent the reader from understanding how the result was reached.
Developing

Is the work disjointed, lacking a clear starting point or logical progression?
- •Presents random snippets of calculation without context
- •Lacks distinct beginning, middle, and end sections
- •Fails to state the problem being solved
- •Information is scattered without discernible order
Communication Mechanics & Visual Standards
15%“The Finish”Evaluates the adherence to academic and visual conventions. Measures the clarity of visual representations (labeling, scaling, readability of graphs/tables) and the quality of written mechanics (grammar, notation standards, citation) explicitly excluding the validity of the math itself.
Key Indicators
- •Formats mathematical notation and variable definitions according to standard conventions.
- •Labels axes, scales, and units clearly in all visual representations (graphs, tables, diagrams).
- •Structures written explanations with correct grammar, spelling, and professional tone.
- •Integrates citations and references for external data or formulas.
- •Organizes layout and hierarchy to enhance readability and flow.
Grading Guidance
To move from Level 1 to Level 2, the student must shift from disorganized or illegible submissions to work that is fundamentally readable. While Level 1 lacks basic structure or contains obstructive errors, Level 2 demonstrates an attempt at organization; graphs exist even if unscaled, and text is decipherable despite frequent mechanical flaws. The transition to Level 3 establishes the competence threshold, where visual and written conventions are correctly applied rather than just attempted. At this stage, axes are labeled with units, standard mathematical notation replaces informal text representations (e.g., using exponents instead of carets), and grammar is sufficiently controlled to prevent confusion. Crossing from Level 3 to Level 4 requires refining the presentation from merely 'correct' to professional and cohesive. Level 4 work integrates visuals seamlessly into the narrative rather than leaving them floating, uses precise academic vocabulary, and ensures consistent formatting throughout the document. Finally, achieving Level 5 distinguishes the work through elegance and sophisticated communication standards. At this level, visual data design actively enhances interpretation (e.g., strategic use of color or data-ink ratio), citation is flawless, and the document flows with the polish of a published academic paper.
