There are 50 levels you may advance to in Star Trek Online, for all 3 factions of Federation, Klingon and Romulan. Every 10 levels you advance a rank up to Level 40; meaning for each rank, there are ten Grades. For example, you may be a Federation player with a rank of Commander, Grade 5; which is equivalent to level 25. Rank names differ by faction but are equivalent to each other.
Level advancement is done by combat, completion of missions or to a lesser extent, by crafting. Leveling unlocks abilities and grants rewards, some specific to your chosen career. Every rank you achieve grants player bonuses, like trait slot unlocks, and a free ship of choice for all ranks except the last. Vice Admiral or equivalent is currently the highest rank attainable, achieved at level 50.
The following table illustrates and compares the levels, achievements and requirements per faction.

You must spend your Skill Points to advance in Rank and Grade. Unspent points do not count toward your rank in Starfleet or the Klingon Empire. If you have enough skill points to increase Rank, but have yet to spend the skill points, you're considered Grade 0 - i.e. you are an LC 0 until you've spent the skill points to become LC 1.
