Is there a word between "beginner/novice" and "intermediate" when describing skill level?

Semi-Intermediate.

I would avoid using Intermediate and say instead “Competent”.

And between Beginner and Competent is “Advanced Beginner”.

Junior level?

Maybe experienced

Sophmore

I’d go with advanced beginner too.

apprenticed, journeyman?

Amatuer, basic

Rookie

Ex-NOOB. Ensign.

I would go with intermediate. What is the skill?

In ballet we call it advanced beginner. It means you know the basic steps, but don’t usually do complicated combinations. It’s a really nice level for adults who want to exercise, know the basics from childhood or learned as an adult, but probably never moved on to performing. Most people at that level want the class to move along fairly quickly, not difficult, so they get a decent workout.

In this case it’s Python programming. I have a solid grasp of the language, but not much experience with beyond simple projects. I can read/write Python, but I’d feel uncomfortable describing my level as “intermediate.”

Right now I’m leaning towards using “moderate,” “intermediate” and “proficient” to describe various technical skills. I would use stars to represent confidence/expertise in these skills, but from what I’ve read, this practice is frowned upon. This is because applicant tracking software that many companies use to import resumes will fail to capture graphical data, tables and other formatting, and may automatically reject your resume before a human ever gets the chance to read it.

^^I use proficient for my Spanish conversational level. I can’t really do business in Spanish nor be an interpreter for something important, but I can get by all day in Spanish in informal situations. My accent is pretty good, rhythm good, it’s just full of bad grammar and once in a while I need to look up words in the dictionary.

FNG?

acolyte

This may depend on what it is you are referring to.
As this is a resume and a self assessment, it is ok to show confidence and state Intermediate. The interviewer will ask a few question possibly if this is something important enough to challenge it.

Wannabe?

I would go with “moderate” or “intermediate”. It’s a skill that you can easily learn with practice and then make yourself more advanced.

I think @Caravanfan makes a good point. You would get up to speed quickly.

Level two. Initiate.

Junior.
