+## How core developers evaluate proposals
+
+The following is a list of considerations that core developers use when deciding
+to accept, close, or leave a proposal open. It is intended to be useful for core
+developers when considering proposals and for proposal-makers in drafting their
+proposals.
+
+#### 1. Does the proposal comply with the rules?
+Read the proposal and check to see that it complies with the above-stated rules.
+If it does not, close the proposal.
+
+#### 2. How much support is the proposal receiving?
+Evaluate the amount of support the proposal is receiving. This is an ongoing
+analysis. If a proposal receives little support at first, it may receive
+additional support later on.
+
+#### 3. Can this proposal be implemented with an addon?
+Evaluate whether it is possible for the proposal to be implemented in an addon.
+If it is possible for the proposal to be in an addon, it is less likely to be
+accepted. 
+
+#### 4. Does this proposal benefit most users?
+Determine whether this proposal benefits all users, or just certain users.
+For example, a feature that can only be used for 3D FPS games is less
+likely to be accepted than a feature that benefits all 3D games.
+
+#### 5. Can this proposal be implemented in a robust, general-purpose way?
+Determine whether the feature can be implemented in a robust way that benefits
+all use-cases. For example, many games use an inventory system, but every game
+implements inventory differently. Accordingly, a proposal for an inventory 
+system will likely not be accepted because it would be impossible for us to 
+implement an inventory system that works for most users that need an inventory
+in their game.
+
+#### 6. Does this proposal help users overcome a limitation?
+Proposals that overcome a specific limitation are more likely to be accepted
+than proposals that are just helpful. In short, need-to-have features will be
+prioritized over nice-to-have features. Further, the core developers prioritize
+changes that enable users to implement features themselves over implementing
+those same features in core.
+
+#### 7. How complex would the proposed feature be?
+A highly complex new feature involving substantial changes to core is less likely
+to be accepted than a feature that can be contained within a single node, or a
+group of nodes.
+
+#### 8. Can the feature be worked around in script with a few lines?
+If the feature is only intended to save users a few lines of code it is unlikely
+to be accepted.
+
+The above considerations are all balanced, no one is more important than another.
+Core developers have discretion to weigh the factors as they see fit.
+
+In addition to the above guideline, consider [this article](https://docs.godotengine.org/en/latest/community/contributing/best_practices_for_engine_contributors.html)
