Should there be spaces after a semicolon in a sentence? For example:
"...minimum/standard requirements for a base diploma;there has been..."
or
"...minimum/standard requirements for a base diploma; there has been..."
Yes. Generally a space is needed after punctuation and before the start of a new word, the exceptions being the beginning of an enclosed pair such as (parentheses) and "quote" marks. Compound word separators such as hyphens - and slashes "and/or" are also exceptions to using a space.
