The computer education certificate of the Audio-visual Education Department is not equal to the calculator certificate, because the computer education certificate of the Audio-visual Education Department is a nationally recognized computer education certificate, which mainly assesses the ability of basic computer operation, network application, computer programming and so on. The certificate is authoritative and professional, and it is one of the important proofs of obtaining professional qualifications in the computer field. Calculator certificate refers to the calculator operation skill certificate obtained through training and examination, which proves that the holder has certain calculator operation ability. It only examines the operation and use of calculators, which is different from the examination scope of computer education certificate. Therefore, although these two certificates are related to calculation, the content of the assessment is different from that of the issuing agency, so the computer diploma of the audio-visual education department is not equal to the calculator certificate.
