The officers were required to submit information on their assets, liabilities and previous work records to State House through Head of Public Service Joseph Kinyua.
Mr Kenyatta said the officers would also take polygraph or lie detector tests in the vetting exercise that was meant to clamp down on corrupt civil servants.
The civil servants were required to submit to the vetting committees certified copies of their mobile money statements, including those of their spouses for the past six months and driving licence numbers.
The officers were also required to submit KRA PIN, ID card numbers, passport numbers, email addresses, and mobile phone numbers among other personal details details.
About 400 procurement and accounting officers, who were subjected to fresh vetting, have been cleared and told to resume duty.
The majority of the officials have received their letters to report to work, while others are awaiting communication.
Only a few officials from the group are yet to receive any communication after several inconsistencies were found in their documents.
“The Presidency has forwarded the list of officers, who successfully went through the vetting exercise and were cleared. The purpose of this letter therefore, is to forward the following names of officers under your entities who are expected to resume duty with immediate effect,” said a letter to senior officers who were suspended in the Ministry of Mining and Petroleum.
