The AI checks your answers before you download

14 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Exclusive Reason for Evaluation

Ensures that exactly one reason for the evaluation is selected from the list in section 6. The form specifies 'CHOOSE ONLY ONE REASON', so the system must prevent the user from selecting zero or multiple reasons. This is critical for correctly categorizing and processing the evaluation for personnel records and career management.

Period Ending Date Format and Logic

Validates that the 'PERIOD ENDING' date in section 4 is a valid date in MM/DD/YYYY format. It also checks that the date is not in the future and is logically sound for an evaluation period. This ensures data integrity and prevents reports from being submitted for invalid or future timeframes.

Employee ID and Name Validation

Verifies that the 'EMPLOYEE ID #' and 'RATE, FIRST NAME, LAST NAME' combination exists and matches an active record in the Coast Guard Direct Access System. This is a fundamental check to ensure the evaluation is being filed for the correct service member. A mismatch would lead to incorrect personnel file entries and significant administrative problems.

Mandatory Comments for Specific Marks

Checks if a comment has been provided for any performance factor that receives a mark of 1, 2, 3, or 7. The form instructions explicitly require written comments to support these marks. Failure to provide justification for unusually low, standard, or high marks would make the evaluation incomplete and difficult to defend or understand.

Mark and Rating Selection Consistency

For each performance factor, this validation ensures the numeric value entered in the 'Mark' column corresponds to the selected radio button rating. For example, if the radio button for a '5' is selected, the 'Mark' field must also contain a '5'. This prevents data entry errors and ensures the intended rating is accurately recorded.

Completeness of All Performance Marks

Verifies that every performance factor on pages 2, 3, and 4 has a numeric mark entered. The instructions state that 'All competencies within each performance factor must be evaluated'. Submitting a form with missing marks would result in an incomplete evaluation of the member's performance.

Common Mistakes in Completing CG-3788B

The ones the AI is built to catch.

Missing Required Written Comments
The form explicitly requires written comments for any mark of 1, 2, 3, or 7, as well as for 'unsatisfactory conduct' and 'not ready/not recommended' for advancement. Raters often overlook this, especially for a mark of 3, assuming it's average and needs no explanation. Failure to provide these comments can lead to the form being rejected by the approving official or personnel support command, delaying the evaluation's finalization and entry into the member's official record. To avoid this, carefully review each mark and ensure a specific, concise comment is provided whenever required by the instructions.
Failing to Attach Separate Page for Critical Comments
The instructions on page 5 mandate that comments for 'Unsatisfactory Conduct' or an advancement recommendation of 'Not Ready' or 'Not Recommended' must be provided on a separate page. A common error is to either forget this attachment entirely or attempt to write these detailed justifications in the limited space on the form itself. This procedural failure can invalidate the negative recommendation or conduct mark, as the full justification is not properly documented, potentially leading to an appeal or requiring the entire evaluation to be redone. Always prepare and attach a separate, clearly referenced page for these specific circumstances.
Forgetting the 'Future Potential' Comments
The 'Future Potential' comment block on page 5 is mandatory for all personnel, yet it is frequently left blank or filled with generic, unhelpful phrases. Raters may overlook it as it appears near the end of the form after the main rating sections. Leaving this section blank misses a critical opportunity to provide context on the member's leadership trajectory and suitability for special assignments, which can negatively impact their consideration for future roles. To prevent this, treat this section as a required field and provide succinct, meaningful comments describing the member's potential for future leadership responsibilities.
Improper Marking of Evaluation Ovals
The instructions on page 1 clearly state to darken the oval completely and not use checkmarks or 'X's. However, many individuals default to using checks or making other stray marks out of habit. This can cause issues with automated scanning systems or lead to ambiguity in the intended rating, forcing the form to be returned for correction. To avoid this, use a pen or pencil to fill in the entire oval for the intended mark, ensuring a clean and unambiguous entry. AI-powered form fillers like Instafill.ai can ensure digital versions are marked correctly and consistently.
Selecting Multiple 'Reason for Evaluation' Options
The 'REASON' section on page 1 explicitly states 'CHOOSE ONLY ONE REASON'. A frequent mistake is selecting multiple options, such as 'SEMI ANNUAL' and 'TRANSFER', if they occur close together. This creates an administrative conflict as the evaluation can only be processed under a single event code. This error will cause the form to be rejected by the processing center, requiring clarification and resubmission. Always determine the single, primary reason for the evaluation based on official guidance and mark only that box.
Inconsistent Ratings Between Raters
The form has a workflow where the Supervisor recommends marks and the Marking Official confirms or changes them. A mistake occurs when the Marking Official changes a mark (e.g., from a 5 to a 4) without documenting the change or discussing it with the Supervisor as required. This leads to a discrepancy between the ovals marked by each rater and the final numerical mark entered, indicating a breakdown in the evaluation process. This can be grounds for an appeal by the member. Approving Officials must ensure any changes are justified and the form is internally consistent before signing.
Vague or Non-Specific Justification Comments
When comments are provided, they are often too vague (e.g., 'Good work' for a 5 or 'Needs improvement' for a 3) and lack the required 'specific examples of performance or behavior.' This fails to properly document the member's performance, making the evaluation less useful for future boards and providing no actionable feedback for the member. To avoid this, raters should cite specific tasks, projects, or observable behaviors that directly support the numerical mark given, adhering to the character limits. This provides a clear and defensible record of performance.
Incorrect Member Identification Information
Errors in the top section of page 1, such as misspelling the member's name, entering the wrong Employee ID, or using an incorrect format for the 'Period Ending' date (not MM/DD/YYYY), are very common. These simple data entry mistakes can cause significant processing delays or result in the evaluation being filed incorrectly in the Direct Access system. To prevent this, double-check all identification data against official sources. Using a tool like Instafill.ai can help by auto-populating and validating this information to ensure accuracy and correct formatting.
Exceeding Character Limits in Comment Fields
The form specifies character limits for comment blocks (e.g., 220 for competencies, 550 for future potential). Raters may write detailed comments that exceed these limits, especially when handwriting or typing in a separate document first. When the data is entered into the official digital system, any text beyond the character limit will be truncated, potentially cutting off critical information or context. To avoid this, be mindful of the limits and write concisely, focusing on the most impactful examples. If the form is a non-fillable PDF, a tool like Instafill.ai can convert it to a fillable version with character counters to prevent this issue.
Missing Signatures or Dates in the Chain of Command
An evaluation is not complete until it is signed and dated by all parties in the correct sequence: Supervisor, Marking Official, Approving Official, and finally the Member. A common mistake is for one person in the chain to forget to sign or date their section, which halts the entire process. This delays the finalization of the report and its entry into the member's record, which can affect eligibility for advancement or special programs. A thorough final review by the Approving Official should be conducted to ensure all signature and date fields are complete before counseling the member.
