can you correct me

The first word of any sentence is always capitalized.  The word “I” is always capitalized regardless of placement. 

When using numbers in a sentence, those from one to nine should be spelled out.  Figures are used when numbering a list, but not in the sentence itself.

The word "ability" should be made plural since you are referring to multiple abilities.

I have to question if you actually have four points.  It seems that the last three are various areas that you intend to improve upon to increase your skill as a psychologist.  I also wonder about your last point.  Psychometry is considered more of a paranormal ability of divining facts about a person by being near them or an object.  Psychometrics is the use of psychological testing.   Since that seems to fit better with the other items, I would change your wording to this:

I will develop the following abilities to increase my skill as a psychologist:
1. Interview technique
2. Psychotherapy
3. Psychometrics
 

1-I will improve my ability to 4 points

2-Technical achievement interview

3-Psychoterapy

4-Psychometry

Those 4 points will improve my knowledge

1-My psychologist skill

2-Technical achievement interview

3-Psychoterapy

4-Psychometry
