Abstract: The study examined instructional space planning for secondary education in Delta State. It adopted the descriptive survey design. The population was all the public and private secondary schools. The sample for the study was 225 schools (public-115, private-110), which is 25% of the population. Stratified random sampling technique was used. A checklist was used to obtain data from the study. Data generated were analysed using percentage. The study revealed that the level of instructional space planning was higher in public schools than in private schools. The study recommended that stringent measures should be put in place to ensure strict compliance to policy provisions in this regard especially among privately owned schools. Public private partnership (PPP) should be pursued in funding education in order to ensure the provision of standardized learning facilities in view of the heavy financial implications.
