* Credential Evaluation: You'll need to have your Jamaican diploma evaluated by a credential evaluation service that's recognized by the US college or technical school you're applying to. These services assess your transcripts and determine if your education meets US standards.
* Specific Admission Requirements: Each college and technical school will have its own admission requirements. Meeting the minimum GPA or equivalent from your Jamaican diploma is only one part; they might require standardized tests like the SAT or ACT, letters of recommendation, and essays.
In short, while your Jamaican diploma is a starting point, you'll need to go through a formal evaluation process and meet all the specific requirements of the individual US institution to gain admission.
