Detailed Grading Criteria
Technical Accuracy & Theoretical Basis
25%“The Science”Evaluates the validity of the fundamental engineering principles, equations, and quantitative data selected for the analysis. Measures whether the student correctly applies the relevant laws of physics, material science, or systems theory independent of the specific case narrative.
Key Indicators
- •Identifies and selects appropriate governing equations and theoretical frameworks for the case conditions.
- •Executes calculations with dimensional consistency and accurate unit conversions.
- •Justifies technical assumptions using established engineering codes, standards, or physical laws.
- •Integrates relevant material properties and system parameters from reliable data sources.
- •Validates analytical results against order-of-magnitude estimates or boundary conditions.
Grading Guidance
Progressing from Level 1 to Level 2 requires the transition from intuitive guessing to the identification of relevant physical laws; the work attempts to use standard equations, though significant calculation errors, incorrect units, or misidentified variables may persist. To cross the competence threshold into Level 3, the student must execute these calculations with dimensional consistency and correct variable selection, producing a technically plausible result where the fundamental engineering logic holds despite minor, non-compounding arithmetic slips. Moving from Level 3 to Level 4 involves contextualizing the theory; the student explicitly justifies necessary assumptions (e.g., assuming steady-state, linear elasticity) rather than applying formulas blindly. Level 5 distinguishes itself through rigorous synthesis and validation. At this stage, the student evaluates the theoretical limitations of the model, integrates multiple engineering sub-disciplines, and verifies results against safety factors or industry standards to ensure the solution is not just mathematically correct, but robustly applicable to the real-world scenario.
Proficiency Levels

- •Explicitly discusses the limitations or boundary conditions of the selected theoretical models.
- •Synthesizes principles from at least two distinct engineering sub-disciplines (e.g., thermal and structural) to explain the case.
- •Validates theoretical results against external data or secondary estimation methods.
- •Identifies and accounts for non-ideal conditions often ignored in standard undergraduate textbook problems.
↑ Unlike Level 4, the work critically evaluates the limits of the applied theories or synthesizes multi-domain concepts rather than just applying a single domain correctly.
Accomplished
Thoroughly applies engineering principles with precision, explicitly justifying the selection of equations and assumptions.
Is the work thoroughly developed and logically structured, with well-supported arguments and polished execution?
- •Explicitly states and justifies all governing assumptions prior to calculation.
- •Calculations are error-free with rigorous adherence to unit consistency and significant figures.
- •Links case study evidence directly to specific variables in the theoretical equations.
- •Provides a clear, step-by-step logical derivation of the quantitative results.
↑ Unlike Level 3, the student explicitly justifies *why* specific theories and assumptions were selected, rather than just using them correctly.
Proficient
Competently identifies and solves the core engineering problems using standard textbook approaches and correct equations.
Does the work execute all core requirements accurately, even if it relies on formulaic structure?
- •Selects the correct fundamental equations (e.g., Bernoulli’s, Ohm’s Law) for the described phenomena.
- •Executes calculations correctly to reach a valid quantitative conclusion.
- •Uses appropriate terminology and symbols consistent with standard engineering conventions.
- •Data inputs from the case are correctly mapped to equation parameters.
↑ Unlike Level 2, the mathematical execution is fundamentally correct and leads to a valid technical conclusion.
Developing
Attempts to apply relevant engineering concepts, but execution is marred by calculation errors, misidentified variables, or conceptual gaps.
Does the work attempt core requirements, even if execution is inconsistent or limited by gaps?
- •Identifies the general physical domain (e.g., correctly identifies this as a stress problem) but selects the wrong specific formula.
- •Contains calculation errors or unit conversion mistakes that skew results.
- •Omits necessary steps or variables in the theoretical explanation.
- •Relies on qualitative description where quantitative analysis was expected.
↑ Unlike Level 1, the work attempts to use relevant scientific principles and equations, even if applied incorrectly.
Novice
Fails to apply fundamental engineering concepts, relying on intuition or irrelevant information rather than theoretical basis.
Is the work incomplete or misaligned, failing to apply fundamental concepts?
- •Uses 'magic physics' (scientifically impossible claims) to explain case events.
- •Fails to include required quantitative analysis or equations.
- •Applies theories totally unrelated to the case facts (e.g., using fluid dynamics for a pure circuitry problem).
- •Demonstrates fundamental misconceptions of basic physical laws (e.g., violation of conservation of energy).
Diagnostic Logic & Solution Feasibility
35%“The Solution”CriticalEvaluates the synthesis of case-specific data with technical theory to identify root causes or design solutions. Measures 'Engineering Judgment'—the ability to interpret ambiguous data, make justifiable assumptions, and propose solutions that are physically and operationally viable.
Key Indicators
- •Synthesizes quantitative case data with relevant engineering theoretical frameworks
- •Identifies root causes by distinguishing symptoms from underlying systemic failures
- •Formulates explicit, justifiable assumptions to bridge specific data gaps
- •Proposes solutions that adhere to physical constraints and operational realities
- •Evaluates trade-offs between technical performance, cost, and safety factors
Grading Guidance
The transition from Level 1 to Level 2 hinges on the shift from descriptive summary to technical application. While Level 1 responses merely restate case facts or rely on lay intuition, Level 2 responses attempt to apply specific engineering formulas or theories to the problem, even if the selection is slightly mismatched or the calculation contains errors. To cross the competence threshold into Level 3, the student must demonstrate functional diagnostic logic; this separates the mechanical, often disconnected application of formulas (Level 2) from a coherent derivation where the theory correctly explains the observed failure. A competent submission solves the right problem using the right physics, whereas lower levels often solve irrelevant sub-problems. The leap from Level 3 to Level 4 involves the integration of ambiguity and operational feasibility. Level 3 work is often 'textbook correct' but idealized, ignoring the messy reality of the case. Level 4 work explicitly handles missing data through justifiable assumptions and validates solutions against real-world constraints like constructability or material availability. Finally, Level 5 distinguishes itself through systems thinking and optimization. Unlike Level 4, which offers a workable solution, Level 5 evaluates complex trade-offs to propose the optimal solution, anticipating secondary effects and addressing long-term reliability versus short-term fixes.
Proficiency Levels

- •Prioritizes root causes based on likelihood or impact rather than just listing them
- •Anticipates potential failure modes or limitations of the proposed solution
- •Integrates cross-disciplinary constraints (e.g., technical, economic, safety) into the design logic
- •Validates assumptions through sensitivity analysis or rigorous theoretical bridging
↑ Unlike Level 4, the work anticipates future implications or failure modes and integrates cross-disciplinary constraints into the solution design.
Accomplished
Provides a robust diagnosis supported by multiple data points and clear theoretical reasoning. Solutions are well-justified, addressing secondary constraints and operational realities beyond just the physics.
Is the diagnosis logically derived from triangulated evidence and the solution thoroughly justified against operational constraints?
- •Triangulates evidence by connecting at least two distinct data points to a single conclusion
- •Evaluates trade-offs (pros/cons) of the proposed solution explicitly
- •Justifies assumptions using logic, standard practices, or case context
- •Addresses implementation details beyond the theoretical concept
↑ Unlike Level 3, the work explicitly evaluates trade-offs and provides evidence-based justification for assumptions rather than just stating them.
Proficient
Correctly identifies probable root causes using standard theoretical models. Solutions are technically viable and meet primary constraints, though they may lack optimization or detailed justification.
Does the student correctly identify the technical root cause and propose a physically viable solution based on standard theory?
- •Links case symptoms to appropriate theoretical concepts correctly
- •States necessary assumptions explicitly, even if not fully justified
- •Proposes a solution that is physically possible and addresses the main problem
- •Distinguishes between the root cause and the symptoms
↑ Unlike Level 2, the diagnosis is technically accurate and the solution is physically viable within the laws of science/engineering.
Developing
Attempts to diagnose based on case data but relies on superficial observations or makes unjustifiable assumptions. Solutions are theoretically possible but may ignore operational constraints.
Does the work attempt to diagnose the problem using case data, even if the reasoning is superficial or the solution lacks operational feasibility?
- •Identifies symptoms (e.g., 'it broke') rather than underlying causes (e.g., 'fatigue stress')
- •Attempts to apply theory but selects the wrong formula or concept
- •Proposes solutions that ignore stated constraints (e.g., cost, time, material availability)
- •Relies on assumptions that contradict case data
↑ Unlike Level 1, the work acknowledges the specific case context and attempts to apply technical theory, even if executed with errors.
Novice
Fails to link symptoms to causes or proposes physically impossible solutions. Work is disconnected from the provided case data or technical principles.
Is the diagnosis missing or disconnected from technical theory, with solutions that are physically impossible or irrelevant?
- •Fails to identify a specific problem or diagnosis
- •Proposes solutions that violate fundamental laws of physics or logic
- •Ignores provided case data entirely in favor of random guessing
- •Offers only descriptive summary without analytical reasoning
Ethical, Safety & Economic Context
20%“The Context”Evaluates the assessment of non-technical constraints surrounding the engineering problem. Measures how effectively the student analyzes safety standards (e.g., OSHA, ISO), ethical implications, environmental impact, and economic cost-benefit ratios.
Key Indicators
- •Identifies applicable regulatory standards (e.g., OSHA, ISO, ANSI) relevant to the specific case context.
- •Calculates economic feasibility using lifecycle cost analysis, ROI, or cost-benefit ratios.
- •Applies professional engineering codes of ethics (e.g., NSPE) to resolve specific moral dilemmas.
- •Evaluates environmental impacts and proposes specific sustainability or mitigation strategies.
- •Synthesizes competing non-technical constraints (e.g., cost vs. safety) to justify final recommendations.
Grading Guidance
Moving from Level 1 to Level 2 requires the student to shift from a purely technical focus to acknowledging the existence of non-technical constraints. While a Level 1 submission often treats the engineering problem in a vacuum, ignoring regulations or costs, a Level 2 submission identifies that safety, economics, and ethics are relevant, even if the application is generic or relies on common sense rather than specific standards. The transition to Level 3 marks the competence threshold, where the student applies formal frameworks correctly. Instead of vague assertions, the student cites specific regulations (e.g., OSHA 1910), performs accurate basic economic calculations, and references specific ethical canons, though these elements may still be treated as isolated checklist items rather than integrated design drivers. To reach Level 4, the student must demonstrate integration and trade-off analysis. The distinction here is the move from compliance to critical evaluation; the student explicitly discusses how safety measures impact the budget or how ethical obligations override economic expediency, addressing the nuance and 'gray areas' of the case. Level 5 distinguishes itself through holistic synthesis and professional judgment. The work proposes innovative solutions that maximize value across all dimensions without compromising integrity, considering long-term lifecycle implications and externalities. At this level, the ethical and economic reasoning mirrors the complexity and foresight expected of a practicing professional engineer.
Proficiency Levels
Distinguished
Demonstrates a sophisticated understanding of how non-technical constraints interact, explicitly analyzing trade-offs between safety, economics, and ethics to justify decisions.
Does the analysis proactively evaluate trade-offs between conflicting constraints (e.g., cost vs. safety) to justify design decisions with specific evidence?
- •Explicitly weighs trade-offs between at least two competing constraints (e.g., 'increasing safety factor X raises cost by Y')
- •Cites specific clauses or subsections of relevant standards (e.g., OSHA 1910.147, ISO 9001:2015) rather than just the general code name
- •Evaluates long-term impacts (e.g., lifecycle assessment, ROI, societal impact) alongside immediate project requirements
- •Synthesizes ethical frameworks (e.g., NSPE canons) with specific design choices
↑ Unlike Level 4, the work actively analyzes the tension and trade-offs between constraints rather than treating them as separate, parallel requirements.
Accomplished
Provides a thorough, detailed analysis of safety, ethical, and economic factors with specific evidence, calculations, and correct application of standards.
Are safety standards, ethical considerations, and economic data detailed, accurate, and directly applied to the specific case?

- •Provides a detailed quantitative cost breakdown or calculated cost-benefit ratio
- •Clearly links ethical obligations to specific stakeholder impacts without prompting
- •Discusses environmental or social impacts with specific context rather than generalizations
↑ Unlike Level 3, the work provides detailed, specific evidence (citations, calculations) for each constraint rather than just identifying them correctly.
Proficient

Does the work correctly identify relevant safety standards, economic costs, and ethical issues without major omissions?
- •Identifies at least one specific, relevant safety or regulatory standard (even if application is standard)
- •Includes basic economic estimates (e.g., total cost, budget adherence) that are factually reasonable
- •Identifies primary stakeholders and potential harms correctly
- •Acknowledges environmental impact if relevant to the prompt
↑ Unlike Level 2, the work cites specific, correct standards and figures rather than relying on generic statements about safety or cost.
Developing
Recognizes the need for non-technical analysis but relies on generic statements, incomplete data, or qualitative assertions where quantitative are needed.
Does the work attempt to discuss safety, ethics, or economics, but lacks specificity, technical depth, or correct citations?
- •Mentions 'safety', 'OSHA', or 'regulations' generally without citing specific relevant codes
- •Provides qualitative economic statements (e.g., 'it will be expensive') without supporting data
- •Lists obvious stakeholders but misses secondary impacts or specific ethical conflicts
- •Attempts to address constraints but treats them as an afterthought
↑ Unlike Level 1, the work acknowledges the existence of non-technical constraints (safety, cost, ethics), even if the analysis is superficial.
Novice
Fails to address non-technical constraints, treats the problem as purely technical, or provides fundamentally incorrect information regarding safety and ethics.
Is the analysis of safety, ethics, and economics missing, irrelevant, or fundamentally incorrect?
- •Omits discussion of safety standards or regulations entirely
- •Ignores economic factors or budget constraints
- •Fails to identify ethical implications or potential harm to stakeholders
- •Focuses exclusively on technical calculations with no context
Technical Communication & Structure
20%“The Report”Evaluates the efficacy of the written artifact as a professional engineering document. Focuses on information hierarchy, clarity of technical prose, citation integrity, and the functional quality of figures, tables, and schematics.
Key Indicators
- •Structures the report using a logical information hierarchy (e.g., Abstract, Analysis, Conclusion) to guide the reader.
- •Articulates technical concepts using precise, objective engineering prose free of colloquialisms.
- •Integrates high-resolution figures, schematics, and tables that directly validate textual claims.
- •Synthesizes external technical standards and literature with consistent citation formatting.
- •Formats document elements (headings, captions, spacing) to ensure professional scannability.
Grading Guidance
Moving from Level 1 to Level 2 requires the student to abandon unstructured, narrative writing in favor of a standard engineering report format; the document must contain distinct, labeled sections (e.g., Problem Statement, Analysis) rather than a continuous wall of text, even if the internal flow remains disjointed. To cross the threshold into Level 3 competence, the writing must shift from conversational to objective; figures and tables must be properly captioned and referenced within the text, and the document must be free of distracting formatting errors that impede basic readability. The leap from Level 3 to Level 4 is defined by the seamless integration of visual and textual data; rather than merely distinct elements, the prose and figures must reinforce each other, with the information hierarchy clearly prioritizing critical technical findings over general background. Finally, distinguishing Level 5 excellence requires a document that functions as a professional industry deliverable; the prose is concise and dense with technical meaning, citations demonstrate a sophisticated synthesis of multiple sources rather than simple attribution, and all schematics or data visualizations are of publication quality, anticipating and answering the reader's technical questions visually.
