Summary of Scoring assessments
Scoring in the Smart Assessment Engine enables ServiceNow customers to convert qualitative assessment responses into quantitative scores. This systematic scoring process evaluates answers across various question types, providing measurable, comparable results that help in understanding assessment outcomes objectively.

Key Features
- Scoring Application: Scores can be assigned to individual questions, subsections, sections, or entire assessments based on predefined criteria.
- Supported Question Types: Includes radio buttons, check boxes, drop-down lists, and numeric fields, with scoring logic tailored accordingly (e.g., assigning scores to options or using numeric responses directly).
- Scoring Functions: Functions such as Sum, Min, Max, Average, and Weighted Average can be applied at assessment, section, and subsection levels; question level supports all except Weighted Average. Only one function can be used per level.
- Normalization: Raw scores can be transformed into standardized ranges or distributions to facilitate consistent evaluation.
- Storage and Visualization: Scores at the question level are stored in the question instance table, while section, subsection, and assessment level scores reside in the scoring metric instance table. Metric mappings link scores to visualization metrics, allowing flexible presentation aligned with application requirements.
Practical Benefits
- Transforms subjective responses into objective data, enabling clearer analysis and informed decision-making.
- Supports alignment of assessments with organizational goals by allowing customizable scoring approaches.
- Simplifies interpretation of assessment results through numerical scoring rather than qualitative review.
- Ensures consistent evaluation of all responses, reducing bias and enhancing reliability.
Scoring in Smart Assessment Engine is a systematic way to evaluate responses to various questions within an assessment. By attributing scores to answers, you can translate qualitative responses into quantitative data, offering a measurable and comparable outcome for each assessment.
Exploring scoring
- For multiselect question types, you can assign scores to options, apply functions, and set question weights.
- For radio question types, you can assign scores to choices and set question weights.
- For number question types, the assessor's numeric response is used as the score.
You can also normalize the scores in which raw scores (the actual score earned on questions) are transformed into a standardized range or distribution. For more information, refer to Normalization in assessment.
Scoring levels
- Assessment level
- Aggregates the scores from all sections and questions within that assessment.
- Section level
- Aggregates the scores from all subsections and questions within that section.
- Subsection level
- Aggregates the scores from all questions within that subsection.
- Question level
- Calculates the scores for each individual question.
Functions, such as Sum, Min, Max, Average, and Weighted average, are available at the assessment, section, and subsection levels. At the question level, all functions except Weighted average are available. However, only one function can be defined at all levels.
- Average
- The sum of all scores is divided by the number of sections or questions.
- Maximum
- The maximum score among all sections or questions is selected.
- Minimum
- The minimum score among all sections or questions is selected.
- Sum
- Scores for all sections or questions are added.
- Weighted average
- A weighted average assigns greater importance to values based on their weight. To calculate it, multiply each question, section or subsections score by its weight, sum up the results, and divide by the total weight.
Scoring results
The final scores are displayed based on the upstream application requirement. They determine how and where the scores are shown to the end user, providing flexibility for score visualization and presentation.
Each section or assessment level has a metric record connected to it through a metric_mapping record. To identify the scores, metric_mapping can be used to check the metric associated with each section, and from the associated metric record, the metric_instance can be located.
- Question level scores are stored in the question instance (sn_smart_asmt_question_instance) table for individual questions.
- Section, subsection, and assessment level scores are stored in the (sn_smart_scoring_metric_instance) table.
Benefits of scoring
id="ul_m4c_r4q_wdc">- Aids in analyzing complex data and making informed decisions by providing clear, objective metrics.
- Aligns assessments with your specific goals and needs because scores can be assigned and calculated in various ways.
- Simplifies the process of interpreting results. Instead of sifting through qualitative data, you can quickly glance at numerical scores to analyze performance.
- Confirms that all responses are evaluated consistently, reducing the likelihood of bias.
