Pennsylvania education officials released Friday performance scores for all 3,200 traditional, charter, cyber and technical schools following complaints about technical errors that delayed it by four days.

School officials complained two weeks ago that technical errors had resulted in many students' tests not being included in the scoring and, as a result, some performance scores are likely to be incomplete.

Schools were able to ask the department to suppress questionable data until corrections are made. Until then, the department said it will compute a rating using available data and issue a revised rating later.

The problem involves the Keystone tests, which were given for the first time statewide in 2012-13.
