Here's a prestige class I made because I wanted to make something that made specialist wizards more of A Thing beyond "I'm a wizard, my focus is ____. That's about it." It'll be getting a playtest as-is in an upcoming campaign, but I'm always happy for more feedback.
Knowledge(arcana) 7 ranks, Spellcraft 7 ranks
Spell Focus in your chosen school of specialization
Must be able to cast 2nd-level arcane spells
Must be a specialist wizard

Skill points per level:
Spellcasting: At each level, you gain new spells per day and an increase in caster level (and spells known, if applicable) as if you had also gained a level in the wizard class. You do not, however, gain any other benefit a character of that class would have gained.
Bonus Feats: At 1st level, you gain Skill Focus (Spellcraft) and Skill Focus (Knowledge(arcana)) as bonus feats.
Supreme Specialization: At 1st level, you must choose an additional prohibited school (other than divination) in exchange for increased benefits of your deeper commitment to your chosen school.
Spell-Like Abilities(Sp): At 1st level and every 2 levels thereafter, you gain a spell-like ability that can be used once per day. At 10th level, you can use your first spell-like ability 3 times per day. Treat the caster level of your spell-like ability as your effective wizard caster level. The spell-like ability you gain is determined by your specialty school.

Focused Arcana: At 2nd level and every four levels thereafter, the caster level of spells you cast of your chosen school increase by 1 (this benefit is cumulative).
Greater Spell Focus: At 3rd level, you gain Greater Spell Focus as a bonus feat. You must apply the feat to your chosen school.
Focused Metamagic: When preparing a spell of your chosen school with metamagic feats, the total increase in spell level is one less than usual, to a minimum of one level higher than the normal spell level.
Adaptive Learning: At 5th level and every two levels thereafter, you may add a spell of your chosen school from another class's spell list of a level one lower than the highest level you can cast to your spellbook. Treat the new spell as an arcane spell when you cast it.
Special Metamagic: Once per day, you can apply a metamagic feat you know to a prepared spell of your chosen school without increasing its spell level.
Greater Focused Metamagic: When preparing a spell of your chosen school with a metamagic feat, the total increase in spell level is two less than usual, to a minimum of one level higher than the normal spell level. This ability replaces Focused Metamagic.
Specialized Resistance: Dispel attempts against spell effects of spells of your chosen school you cast have their DC increased by 5.
Versatile Specialization: At 10th level, you have focused on your chosen school to the point that casting its spells are second nature. If you prepare a spell of your chosen school, you may spend that spell slot to cast another spell of your chosen school of the same spell level you prepared that day, regardless of whether the other spell has been cast.
