The aim of the study is to determine the offsite construction skill needs of block-laying and concreting students for optimal productivity and sustainability in covid-19 era in Rivers State. The study was guided by one research question and one hypothesis. The research method adopted was a descriptive survey research design. The population of the study consisted of seventy-five industrial supervisors and 15 block-laying and concreting teachers in the technical colleges in Rivers State. The entire population were used for the study considering the manageable size. A structured five point Likert scale questionnaire titled Offsite Construction Skill Needs in Block-Laying and Concreting for Optimal Productivity and Sustainability in Covid-19 Era in Rivers State (OCSNBCPSCERS) was developed to elicit responses from the respondents. The validity of the instrument was carried out by three lecturers in the department of Industrial Technical Education who carried out a face and content validity of the questionnaire items. The reliability of the instrument was determined by administering copies of the instrument to five block-laying and concreting teachers in Federal Science and Technical College Ahoada and ten builders who were not part of the sample used for the study. Thereafter, the internal consistency of the instrument was determined using Cronbach Alpha reliability coefficient and a reliability coefficient .89 was obtained indicating that the instrument was highly reliable. The research question was answered using mean while an independent sample t-test was used to test the null hypothesis at .05 level of significance. For answering the research question, a criterion mean of 3.50 was established. Mean responses of 3.50 and above were needed while mean responses below 3.50 were not needed. For testing the hypothesis, when the calculated t-value is below the critical table value the null hypothesis was accepted otherwise the hypothesis is rejected. The study revealed that the ability to read and interpret working drawings, operate mechanical equipment, hoist, assemble and erect  components, prepare and apply non shrink mortars to seal gap, adjust the panel in position and secure, ensure joint widths are consistent before grouting, set up formwork for casting joints are the skills needed for offsite construction. Finally, the researchers recommended that block-laying and concreting teachers should be retained on the various offsite construction techniques and materials. The National Board or Technical Education (NBTE) should review the block-laying and concreting curriculum and include offsite construction methods as part of the current trends in the construction industries for optimal productivity and sustainability.
