CDR DTR · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Food and Nutrition Sciences

  • Define digestion, absorption, and transport mechanisms for each macronutrient and trace the pathway from ingestion to cellular use

  • Calculate energy needs using Mifflin-St Jeor, Harris-Benedict, and indirect calorimetry values, then compare the three outputs for the same case

  • Explain glycolysis, TCA cycle, gluconeogenesis, lipolysis, and ketogenesis and state the hormonal triggers for each

  • Differentiate fiber types, glycemic response, protein quality measures (PDCAAS, DIAAS), and lipid classification by structure

  • Draw a one-page metabolic map linking fed-state and fasted-state pathways

Your checkpoint

Completed one-page hand-drawn metabolic map plus a 30-item self-quiz on macronutrient science scored and logged with corrections

Week 2

Food and Nutrition Sciences

  • Tabulate the function, deficiency signs, toxicity risk, and key food sources for 20 vitamins and minerals

  • Interpret water and electrolyte balance, acid-base relationships, and hydration assessment indicators

  • Identify nutrient-drug and nutrient-nutrient interactions for at least 12 common medication classes

  • Apply food science principles (Maillard browning, emulsification, pH effects, freezing/thawing) to predict nutrient retention and quality changes

  • Solve stoichiometry-style problems converting food composition data into nutrient intake values

Your checkpoint

A 25-row nutrient reference table (function, deficiency, toxicity, source) built from memory first, then verified and corrected

Week 3

Nutrition Care for Individuals and Groups

  • Apply the nutrition care process: assess, diagnose (write PES statements), intervene, monitor, and evaluate for 5 short vignettes

  • Interpret anthropometrics, biochemical indices, clinical signs, and dietary intake data to prioritize nutrition problems

  • Compare nutrient needs across the lifecycle (pregnancy, lactation, infancy, childhood, adolescence, older adulthood)

  • Write 10 correctly formatted PES diagnostic statements using approved terminology

  • Select and justify the appropriate malnutrition screening and assessment tool for a given setting

Your checkpoint

Ten PES statements written from vignettes, self-scored against an accuracy checklist at 90% or better

Week 4

Food and Nutrition Sciences & Nutrition Care for Individuals and Groups

  • Construct medical nutrition therapy plans for diabetes, cardiovascular disease, chronic kidney disease, and obesity using current evidence-based recommendations

  • Differentiate enteral and parenteral nutrition indications, formula selection, delivery routes, and complication monitoring

  • Apply behavior-change and counseling frameworks to build a realistic client education plan

  • Calculate tube feeding and TPN orders including goal rate, water flushes, and macronutrient distribution

  • Identify refeeding syndrome risk factors and outline monitoring parameters

Your checkpoint

Three complete written case studies (assessment through evaluation) plus a timed 40-question Domain 1 and 2 practice test with a written error analysis

Week 5

Foodservice Systems

  • Compare conventional, commissary, ready-prepared, and assembly-serve production systems on cost, labor, and quality tradeoffs

  • Build a HACCP plan with hazard analysis, critical control points, critical limits, monitoring, and corrective actions for one menu item

  • Apply food safety time-temperature standards, foodborne pathogen characteristics, and sanitation procedures to inspection scenarios

  • Calculate recipe yield, conversion factors, and portion cost for a standardized recipe

  • Evaluate equipment selection and layout decisions for workflow efficiency and energy use

Your checkpoint

A complete HACCP plan for a single high-risk menu item, including flow diagram, CCPs, limits, monitoring log, and corrective actions

Week 6

Management of Food and Nutrition Systems

  • Distinguish management functions, leadership styles, and motivational theories and match each to a workplace scenario

  • Draft a department operating budget with labor, food, and supply line items and compute variances from actuals

  • Apply human resource processes: recruitment, orientation, performance appraisal, discipline, and union/labor considerations

  • Design a quality improvement and customer satisfaction measurement approach for a foodservice operation

  • Compare regulatory, accreditation, and reimbursement requirements affecting nutrition services

Your checkpoint

A one-department operating budget with a written variance analysis of at least three line items and recommended corrective actions

Week 7

Food and Nutrition Sciences & Nutrition Care for Individuals and Groups & Foodservice Systems & Management of Food and Nutrition Systems

  • Complete a full-length timed mock examination under test-day conditions with no reference materials

  • Score by domain and rank weakest to strongest performance areas

  • Re-teach the two lowest-scoring content areas using targeted study blocks and new practice items

  • Build a personal error log categorizing misses as knowledge gap, misread question, or calculation error

  • Rehearse calculation set: energy needs, IBW, tube feeding, recipe yield, and budget variance under time pressure

Your checkpoint

Full mock exam score report by domain plus a categorized error log naming the top three recurring failure patterns

Week 8

Nutrition Care for Individuals and Groups & Management of Food and Nutrition Systems

  • Retarget the highest-yield weak areas identified in the error log with focused review and spaced retrieval practice

  • Answer 50 mixed rapid-fire items daily and review every rationale, right or wrong

  • Condense each domain into a single review sheet limited to facts you have personally missed

  • Simulate exam-day logistics: timing strategy, break planning, and question-flagging rules

  • Complete a final timed mock exam and verify performance is at or above target

Your checkpoint

Four one-page domain review sheets built only from personal missed items, plus a final timed mock exam scored at 80% or higher

Milestones

Week 2: Score 80% or better on a 30-item Domain 1 science quiz and confirm the nutrient reference table is complete with all corrections noted

Week 4: Complete all three case studies and score 75% or better on a timed 40-question Domain 1 and 2 practice test

Week 6: Submit the HACCP plan and operating budget deliverables, and score 75% or better on a 30-question Domain 3 and 4 practice test

Week 7: Finish the full-length timed mock exam and produce a domain-by-domain score report with three named weak areas

Week 8: Score 80% or higher on the final timed mock exam and confirm all four one-page review sheets are complete
