[Workflow](https://guides.matecat.com/workflow?hsLang=en) # Custom Quality Frameworks ## Create and manage custom quality frameworks A quality framework is a **combination of error categories and severities** used to label issues found in a translation, along with **Error per Thousand Words (EPT) thresholds**. More details about these combinations are provided below. Matecat has a default quality framework that it uses for all projects for which a custom quality framework is not chosen.  **![quality framework](https://guides.matecat.com/hs-fs/hubfs/quality%20framework.png?width=670&height=516&name=quality%20framework.png)** ### **Using a customized quality framework** You can **use custom quality frameworks** to suit your specific requirements by modifying the EPT thresholds and the values in the evaluation grid. #### **EPT thresholds** The[scoring system](https://guides.matecat.com/quality-report-in-matecat?hsLang=en) used in Matecat is Error per Thousand Words (EPT). EPT thresholds **determine whether projects pass or fail at each revision stage** based on their EPT score. The default values are 8 for R1 and 5 for R2.  A project **passes** a certain revision stage **when its EPT score in that stage is below or equal to the set threshold**. Any value exceeding the threshold will result in a "Fail," while values below the threshold will secure a "Pass". You can change the thresholds to tailor them to your needs. ![](https://guides.matecat.com/hs-fs/hubfs/undefined-2.png?width=670&height=297&name=undefined-2.png) #### **Evaluation grid** The evaluation grid **manages categories and severity levels** during[revision](https://guides.matecat.com/revising-your-translation-jobs?hsLang=en). Categories are used to categorize the type of error found, while severity levels measure the gravity of the error. Severity levels are category-specific, meaning you can assign different weights to the same severity level depending on the category. ![](https://guides.matecat.com/hs-fs/hubfs/undefined-3.png?width=670&height=467&name=undefined-3.png) You can edit, move up/down, delete and add new categories. Categories have both a name and a description; when creating or editing a category, you can manage both. ![](https://guides.matecat.com/hs-fs/hubfs/undefined-4.png?width=670&height=442&name=undefined-4.png) You can also add a severity if you need. ![](https://guides.matecat.com/hs-fs/hubfs/undefined-Oct-31-2025-02-07-26-7767-PM.png?width=670&height=355&name=undefined-Oct-31-2025-02-07-26-7767-PM.png) The new severity will be added to the grid. ![](https://guides.matecat.com/hs-fs/hubfs/undefined-Oct-31-2025-02-07-47-1928-PM.png?width=670&height=316&name=undefined-Oct-31-2025-02-07-47-1928-PM.png) If necessary, you can also remove severities. You can decide to remove a severity only for specific categories, in which case it will still be available for the others. ![](https://guides.matecat.com/hs-fs/hubfs/undefined-Oct-31-2025-02-08-12-9943-PM.png?width=670&height=468&name=undefined-Oct-31-2025-02-08-12-9943-PM.png) ![](https://guides.matecat.com/hs-fs/hubfs/undefined-Oct-31-2025-02-08-23-8297-PM.png?width=670&height=312&name=undefined-Oct-31-2025-02-08-23-8297-PM.png) Alternatively, you can remove the severity entirely from all categories. ![delete severity](https://guides.matecat.com/hs-fs/hubfs/delete%20severity.png?width=670&height=518&name=delete%20severity.png) ![](https://guides.matecat.com/hs-fs/hubfs/undefined-Oct-31-2025-02-09-00-6191-PM.png?width=670&height=538&name=undefined-Oct-31-2025-02-09-00-6191-PM.png) **Any changes to the default quality framework will be highlighted in blue** and will trigger the option to **save the current settings either as a new configuration or, if you are editing an existing configuration, as a new version of it.** Even if you **don’t save the configuration**, the **new settings are still applied to the project** you are currently creating. ![](https://guides.matecat.com/hs-fs/hubfs/undefined-Oct-31-2025-02-09-27-4688-PM.png?width=670&height=346&name=undefined-Oct-31-2025-02-09-27-4688-PM.png) To **use a custom quality framework in a project template**, first **save the settings in a configuration** (either new or existing). If you **create a new configuration or edit an existing one that is not yet linked** to the current project template, **link the configuration to the template and save** the template. However, if you **edit a configuration that is already linked to the current project template**, you don’t need to save the template again, as **the changes take effect automatically**. ![new quality framework](https://guides.matecat.com/hs-fs/hubfs/new%20quality%20framework.png?width=670&height=434&name=new%20quality%20framework.png)   - [Getting Started](https://guides.matecat.com/getting-started?hsLang=en#main-content) - [Matecat overview](https://guides.matecat.com/getting-started?hsLang=en#matecat-overview) - [Data security](https://guides.matecat.com/getting-started?hsLang=en#data-security) - [Workflow](https://guides.matecat.com/workflow?hsLang=en) - [Machine Translation](https://guides.matecat.com/machine-translation?hsLang=en) - [Language assets](https://guides.matecat.com/language-assets?hsLang=en#main-content) - [Translation Memories](https://guides.matecat.com/language-assets?hsLang=en#translation-memories) - [Termbase](https://guides.matecat.com/language-assets?hsLang=en#termbase) - [Project Analysis](https://guides.matecat.com/project-analysis?hsLang=en) - [Editor](https://guides.matecat.com/editor?hsLang=en#main-content) - [Revision](https://guides.matecat.com/editor?hsLang=en#revision) - [Settings](https://guides.matecat.com/editor?hsLang=en#settings) - [Workspace](https://guides.matecat.com/workspace?hsLang=en) - [Tags](https://guides.matecat.com/tags?hsLang=en) - [Working faster](https://guides.matecat.com/working-faster?hsLang=en) - [Quality check tools](https://guides.matecat.com/quality-check-tools?hsLang=en) - [Advanced Features](https://guides.matecat.com/advanced-features?hsLang=en) - [Matecat utilities](https://guides.matecat.com/matecat-utilities?hsLang=en) - [Google integration](https://guides.matecat.com/google-integration?hsLang=en) - [Contact us](https://guides.matecat.com/contact-us?hsLang=en) [![Chill listening crop-3](https://guides.matecat.com/hubfs/logo_matecat_small-1.svg "Chill listening crop-3")](https://www.matecat.com) The Matecat support team is available Monday/Friday from 9:00 to 19:00 CET.
