QC Review Reason Codes: Accuracy

Reason Code



Incomplete answer

A complete answer starts with the problem's objective OR introduces available data/ information Or the right approach and then adds all necessary steps/supporting explanations until the answer is complete

To avoid this expert need to read the question details carefully. Attempt questions if fully

Incorrect answer

The correct answer to a problem is one that is error-free in conceptual statements, calculations, graphs, diagrams, tables, formulas, etc., whatever it takes to accomplish the goal. This reason code is applied if the solution has wrong calculations/ wrong final answer/wrong content.

Expert need to double check the solution whether correct concept, explanation, calculations provided or not before submitting. Also attempt questions if

Typo errors

A meaningful answer is possible if there are no typos in statements/expressions/ substitutions/diagrams/tables/graphs. Select this reason code if the solution has typo

Avoid any short of typos during creating the solution. Typo errors may cause

Formula error

The correct formula conceptually drives the major chunks of the problem to interlink with variables or steps. This will enable them to begin substituting, to assist in the analytical portion, etc. This reason code is applied if the solution uses a wrong formula or a formula that does not apply to the given conditions.

Double check the formulas applied in the solution to avoid formula errors. More care required as using wrong formulas lead to wrong solutions.

Incorrect graph/ diagram/tables/ charts

As per the requirements of the problem, adding objects such as graphs, diagrams, tables, and charts to an answer will enhance its value and improve students' understanding. This reason code is applied If the solution has errors in graphs/diagrams/

Care should be taken to provide neat and well labelled diagrams to avoid this kind of errors.

Programming errors

Programming consists of understanding a need and constructing a set of instructions to execute and to obtain the desired result.

There are various programming languages to use based on the question's requirements. If the solution has errors in the program provided in the solution has syntax/logical

Before submitting the answer, it is suggested to execute the code/ program.

to avoid any errors.

Grammatical errors

Meaningful sentences & conceptually correct statements are possible if the answer does not contain any grammatical errors. This reason code is applied if the solution has English language grammar or spelling errors.

A solution cannot be called a good solution if it has language errors. It is suggested to use proper language checkers if required to

Units / Notations / Significant figures errors

Often, when a problem is being solved, there will be standard units, notations, and significant figures that should be used as per the problem. The reason code is applied if the solution contains errors related to unit conversions, units, notations of parameters, significant figures or rounding off values.

Follow the same unit system provided in the question. Check the solution for units, notations, conversion factors and significant figures or rounding off

Calculation errors

Calculation refers to the process of determining a value or expression through logical or mathematical steps. Correct calculation plays a vital role in finding intermediate values and final conclusions.

Calculation errors lead to wrong final answer, so double check the calculation error before submitting answer.

QC Review Reason Codes: Explanation


Reason Code



Missing formulas

Formula conceptually drives major part of the problem to interlink with variables or steps. This will enable them to begin substituting, to assist in the analytical portion, etc. This reason code is applied if the solution does not show the

Make sure include relevant formulas to the solution that help to understand the solution better.

Missing supporting statements

Conceptual statements and sentences are needed to sustain the richness of explanation and maintain logical flow throughout the entire process. Authors should place reasoning or supporting statements wherever required in

Make sure to include supporting statements that help to understand the solution better.

Table/Plot missing

Specifically, for certain problems, tables and plots are mandated to accomplish the objective, and the tables or plots can be created in a step based on the previous steps / descriptions in the answer or as a step to initiate follow-up steps

Without table/plot solution is incomplete. Use available SQnA tools to draw the plots/diagrams in support of the solution.


To show cohesion, an answer must be organized by maintaining logical connections between every line and adding all necessary explanations.

Make sure to maintain logical flow within the solution. Using SQnA blocks/tools this is possible

Diagram missing

Diagrams can be part of an explanation if the question asks for them, as they also contribute to the completeness of an answer.

Without supporting diagram solution is incomplete, so make sure to upload relevant diagram before submitting. Use SQnA drawing tool

Missing Steps/ calculations

Calculations / steps are crucial to understand how intermediate conclusions are placed in an answer. Authors should demonstrate how a calculation or work was performed to produce

Create solutions with detailed steps and complete calculations steps.

Using SQnA tools step by step solution can be created

QC Review Reason Codes: Concept

Reason Code



Incorrect method

For each problem, there is a standard procedure to follow throughout the solution. This is based on the objective of the problem, depth of concept, need for explanation, tables, graphs, diagrams, and complexity involved in problem solving and so many other factors. A deviation or omission from this method should

Make sure to use apply the correct method while solving. If asked to use a specific method use that method instead of using generic method.

Conceptual errors

Using the correct approach, explanations, formulas, graphs, tables, diagrams, and calculations, etc., with all the necessary steps, this will lead to a conceptually correct solution. Any error occurring in an answer that contradicts the concepts, logics, or rules that must be followed in

Make sure to avoid conceptual errors while creating the solution.

QC Review Reason Codes: Structure


Reason Code



Missed Step-by- Step approach

By grouping logically connected conceptual parts, calculations, statements, and content pieces and writing them in each step, the Step-by-Step blocks make it easy to break down an answer into logical steps. In case author is unable to breakdown the answer into multiple steps by using step- by-step block then QC reviewer could label them as ‘Missed Step-

For lengthy solutions create solution in multiple steps instead of adjusting in single step to avoid quality issues.

Editor tools not used

To provide structured Q&A answers by all subject specific experts, expert 2.0 planform provides various tools / editors, such as math-in-text, math equation renderer, math inline equation renderer, table editor, journal entry table, t-accounting table, code snippet inserter, chemistry block, circuit editor, drawing or illustration tool.

Authors should use the appropriate editor based on the

Do not upload images into SQnA step blocks. Instead create solution using SQnA tools like Equation render, Drawing tool, Table template etc as applicable.

Inappropriate explanation

An explanation block is placed between steps to provide an overview or description, or to ensure clarity with supporting statements / formulas. In the case where the author provided irrelevant information about the above step or irrelevant / vague

Do not include calculation steps in Explanation block, instead provide explanation for the calculations done is steps.




Inappropriate final answer



At the end of the answer, Expert

2.0 has enabled a separate section to provide the conclusion or final answer. It is advisable to write only the final answer or conclusion based on the objective of the problem. Also, for multiple subpart questions, the author must provide answers for all subparts at one go. This block should not include any other details, steps, calculations, or comments. Select this reason code if the solution has irrelevant statements/comments in the final answer block. Or a part of the



Though final answer is calculated in steps, expert should explicitly mention final answer in the final answer block separately, avoiding which may lead to quality issues. Do not write solution steps in final answer block.

Skipped explanation

Expert 2.0 answering editor has a separate block to provide additional explanations followed by a step. Here, it is recommended to write an overview or description or to ensure clarity through supporting statements / formulas for the above step. 'Explanation block' is

As per the length and breadth of the solution add explanation wherever applicable. Skipping explanation for lengthy solution may lead to quality issues.

 QC Review Reason Codes: Answering Guidelines

Reason Code



Formatting / Alignment issue

The answer may contain a variety of content objects. Each of them may expect a required format or style, font size, alignment, margin, etc., to create an appealing

Created solution should be in proper format. SQnA tool like Equation render help us to avoid formatting/ alignment errors.

Missed to use Math-in-Text

Math-in-Text is a tool utilized for 2 line or 3-line calculations where the expression starts with a formula followed by substitutions and then the results are auto- calculated. Generally, this tool is

Math-in-text one of the SQnA tool using which basic calculation can be done in less time. So, it is suggested to use the tool wherever applicable.

Missed to use Equation Render

Inline equation renderer and Math Equation renderer are part of the category Math Equation Renderer, and they are valuable tools for inserting math expressions & equations in multi-line

Equation render is one of the SQnA tool using which multiple math steps can be put in proper format and alignment. It is suggested to use the tool wherever applicable to create a well-structured solution.

Uploaded Improper Image

Expert 2.0 enabled various editors to insert tables, diagrams, math expressions, chemical equations, chemical block diagrams, and electric circuits, among others.

Instead of using the current tool, when an author uploads content in image format, it will come

Creating solution with relevant SQnA tools is recommended. Do not uploaded solution in image format.

T accounting not used

'Journal entry tables' and 'T- accounting tables' are available as templates to update entries based on question requirements and complete answers, and these templates facilitate auto- generated results. Authors are supposed to use in-built templates

T accounting is one of the good tools to create Accounting based solutions. It is suggested to use this tool to avoid errors.

Table templates not used

There are a lot of accounting specific table formats available in Table templates. These include budget tables, Income statements, Profit/loss statements, balance sheets, etc., that allow users to insert required table formats based on question requirements. These templates generate autogenerated results. Authors are supposed to use in-built

Table template is one of the SQnA tool, using which data can be put in a table format. Experts should use Table templates as per the question requirement.

Multipart questions rule not followed

According to the Multi-part question rule, if there are multiple questions in a post, either the first question in the post or the requested question by the student should be answered. If the author has answered a different question than the first question or a question requested by the student, the QC reviewer should

In case of multiple questions, expert should answer the first one or the specific question asked by student. In case of subpart type questions, expert need to answer all questions to avoid quality issues.

Text Editor not used

Text parts/sentences must be typed in a text editor. This reason code is applied if the author

Text editor is one of the SQnA tool helpful to create text-based solutions. It is suggested to use it

Chem Inline Equation tool not used

Chemistry equations / expressions should be written using the Chem Inline Equation tool. This reason code is applied if the author uploaded handwritten or typed
