Subject: Formal Complaint Regarding Grading Inconsistency in "Advanced Research Methods" (RES 7001) - Student ID [Your ID] 

Dear [Recipient's Name],

I am writing to file a formal complaint regarding my final research paper grade in the module "Advanced Research Methods" (RES 7001), taught by Dr. [Lecturer's Name]. I believe the grade of 65% is inconsistent with the marking criteria and the university's academic policies, as I will outline below. 

The assignment was submitted on [Date of Submission]. The marking criteria for the paper explicitly stated that clear and concise communication of findings would be a key factor in the evaluation. My paper, which was marked by Dr. [Lecturer's Name], received critical feedback stating a lack of clarity, despite several peers and a writing tutor confirming the clarity of my argument. On [Date], I met with Dr. [Lecturer's Name] to discuss the feedback, but the conversation did not result in a satisfactory explanation of the grade based on the published rubric. 

This situation appears to violate Section 4.3 of the university's "Academic Appeals and Grievances Policy," which requires marks to be awarded transparently and in line with published criteria. The disparity between the feedback and the rubric’s stated requirements suggests that the criteria were either not applied correctly or were misinterpreted during the evaluation process.

The grade of 65% on this final paper has a significant negative impact on my overall module result and, consequently, my final academic standing. I am concerned that an incorrect grade on a core module will adversely affect my master’s program progression.

While I appreciate Dr. [Lecturer's Name]'s time during our meeting on [Date], the issue remains unresolved. As a result, I am formally escalating this matter and request a review. 

To resolve this issue, I formally request that my research paper be re-evaluated by an independent, qualified marker from within the department, as per the established university procedure for re-marking. 

I have attached the following documents for your consideration:

• My submitted research paper
• The assignment marking rubric for RES 7001
• Relevant email correspondence with Dr. [Lecturer's Name]
• Evidence from the writing tutor outlining their assessment of my paper's clarity

 I look forward to your prompt response and am confident this matter will be resolved fairly and in accordance with university policy.

Yours sincerely,
[Your Handwritten Signature, if applicable]
